(1)  This Registration Statement relates to a total of 737,174 Warrants to
     be offered for sale by certain selling security holders.  These
     Warrants were issued as a component of equity units issued by the
     Company in a private placement that closed in September, 1995.  Each
     Warrant is  exercisable to purchase one share of Common Stock at $.375
     per share.  A market currently does not exist for any of the Warrants.

(2)  No registration fee is due for the Warrants under Rule 457(g) because

     underlying the Warrants.

(3)  This Registration Statement relates to the 887,174 shares of Common
     Stock issuable upon the exercise of all of the following outstanding

     per share.

     (b)  These shares are issuable upon the exercise of Warrants at $.80
     per share.

(5)  These shares of Preferred Stock were issued by the Company in a
     private placement that closed in July, 1996.  This Registration
     Statement relates to the shares of Preferred Stock to be offered for
     sale by certain selling security holders.  No market currently exists
     for the Preferred Stock.  A registration fee is not due for the
     Preferred Stock because this Registration Statement also relates to
     the Common Stock underlying the Preferred Stock.

(6)  The Preferred Stock is convertible into shares of Common Stock at the
     following conversion rates (subject to adjustment): (1) prior to the

                                                                  Page iii

     relate to shares previously issued by the Company upon the exercise of
     certain options granted by the Company to certain officers and
     directors and 12,000 of these shares relate to shares issued in lieu
     of a sales bonus to a former employee of Chase Packaging Corporation,

Statement shall become effective on such date as the Commission, acting
pursuant to said Section 8(a), may determine.

The Preferred Stock is traded on the NASDAQ SmallCap Market under the symbol 
"TGCIP," and the Common Stock is traded on the NASDAQ SmallCap Market under 
the symbol "TGCI."  On May 19, 1997, the average of the high and low prices

Selling Security Holders in the over-the-counter market, in private 
transactions, or, otherwise, through broker dealers. These sales will 
be made either at market prices prevailing at the time of the sale 
or at negotiated prices.  The broker dealers may act as agents for
the Selling Security Holders or may purchase any of the securities as
principal and thereafter sell such securities from time to time in the
over-the-counter market or otherwise at prices prevailing at the time of
sale or at negotiated prices.  Broker dealers used by the Selling Security
Holders may be deemed to be "underwriters" as defined in the Securities Act
of 1933.  In addition, the Selling Security Holders may be deemed to be
underwriters within the meaning of the Securities Act of 1933 with respect
to the securities offered thereby.      
    
No person is authorized to give any information or to make any
representations other than those contained in this Prospectus in connection
with the offer contained herein and, if given or made, such information or
representations must not be relied upon as having been authorized by the
Company or any Selling Security Holder.  This Prospectus does not
constitute any offer to sell or a solicitation of an offer to buy any 
securities other than the registered securities to which it relates.  This

                                                                  Page vi
Prospectus does not constitute an offer or solicitation by anyone in any
state in which such offer or solicitation is not authorized or in which the
person making such offer or solicitation is not qualified to do so or to
any person to whom it is unlawful to make such offer or solicitation.  This
Prospectus shall not constitute an offer to sell or a solicitation of an
offer to purchase any securities in any jurisdiction in which such
transactions would be unlawful.  The delivery of this Prospectus at any
time does not imply that the information herein is correct as of any time
subsequent to the date hereof.

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES

(1)  The Warrants and shares of Preferred Stock offered hereby by Selling
     Security Holders and the shares of Common Stock offered hereby by
     Selling Securities Holders will be offered at either prevailing market
     prices or at negotiated prices; therefore, the price to the public
     cannot be determined at this time.


                                                                  Page vii
(2)  There is no underwriter.  It is anticipated, however, that the broker- 
     dealers engaged by the Selling Security Holders will receive
     commissions or discounts from Selling Security Holders in amounts
     negotiated immediately prior to the sale.  The amount of any such
     commissions, which will be paid by the Selling Security Holders,
     cannot be determined at this time.

(3)  These securities are offered on behalf of Selling Security Holders of
     TGC, and, therefore, no proceeds from the offering of such securities
     will be paid to TGC.  

(4)  Of the 9,456,680 shares of Common Stock to which this Prospectus
     relates, 737,174 shares are issuable upon the exercise of outstanding
     Warrants issued in the 1995 private placement.  Each Warrant is
     exercisable to purchase one share of Common Stock at $.375 per share.
     Assuming all outstanding Warrants are exercised, the Company will
     receive $276,440.25.  An additional 150,000 shares of Common Stock are
     issuable upon the exercise of Warrants issued, together with notes, by
     the Company to certain officers and directors of the Company.  Each
     Warrant is exercisable to purchase one share of Common Stock at $.80
     per share.  Assuming all such warrants are exercised, the Company will
     receive $120,000.00.  Of the remaining 8,569,506 shares of Common
     Stock to which this prospectus relates, the Company will not receive
     proceeds from the 7,669,000 shares issued upon conversion of all the
     Preferred Stock nor will the Company receive proceeds from the 900,506
     shares offered hereby by certain selling security holders.


             The date of this Prospectus is July 2, 1997.

The Company

In April, 1980, Supreme Industries, Inc., formerly ESI Industries, Inc.,
("Supreme") formed a wholly-owned subsidiary which acquired certain
equipment, instruments, and related supplies of Tidelands Geophysical Co.,
Inc. ("Tidelands"), a Houston-based corporation which was organized in 1967
and was engaged in the business of conducting seismic, gravity, and
magnetic surveys under contracts to companies in the exploration for oil
and gas.  In July, 1986, Tidelands' name was changed to TGC Industries,
Inc. ("TGC").  On June 30, 1986, the Board of Directors of Supreme and TGC
approved a spin-off whereby substantially all of the shares of TGC owned by
Supreme were distributed as a stock dividend to Supreme security holders. 

   
On July 30, 1993, TGC acquired, through a wholly-owned subsidiary, Chase
Packaging Corporation ("Chase"), a specialty packaging business,
principally supplying products to the agricultural industry, through the
purchase of certain assets of the Chase Packaging division of Union Camp
Corporation.  On June 24, 1996, the Board of Directors approved the
spin-off of Chase whereby all of the shares of Chase owned by TGC would
be distributed as a stock dividend to the shareholders of the TGC Common 
Stock and, on an as if converted basis, the TGC Preferred Stock, 
effective July 31, 1996.  The record date for the spin-off was July 15, 
1996; however, the TGC Common Stock and Preferred Stock traded with "due 
bills" from the record date through the distribution date of the Chase 
Common Stock, which date was March 7, 1997.  
                                                                      Page 2

Since its formation, TGC has engaged in the domestic geophysical services
business principally through conducting seismic surveys and to a lesser
extent through sales of gravity information from the Company's Data Bank to
companies engaged in the exploration for oil and gas in the United States. 
Geophysics is the study of the structure and composition of the earth's
interior and involves the measuring and interpretation of the earth's
properties with appropriate instruments.  Such studies are generally
conducted by means of surveys performed by field crews employing seismic,
gravity, or magnetic instruments to acquire data which is then interpreted
by various means to obtain useful information for oil and gas companies. 
The two survey techniques used by the Company in acquiring geophysical data
are seismic and gravity.  Land seismic surveys are the Company's principal
method of data acquisition and are by far the most widely used geophysical
technique.  TGC's seismic crews use dynamite as the primary energy source
for such surveys.

Industry Overview

Seismic data is the principal source of information used by geoscientists
to map potential oil and gas bearing formations and the geologic structures
that surround them.  Seismic data is acquired over a wide area by directing
sound waves into the earth and measuring the response as these sound waves
reflect off subsurface geologic formations.  In the past, the 2-D seismic
survey was the standard data acquisition technique used to describe
geologic formations over a broad area.  2-D seismic data can be visualized
as a single vertical plane of subsurface information, and 2-D seismic
surveys typically require 120 recording channels.  Data gathered from a 3-D
seismic survey is best visualized as a cube of information that can be
sliced into numerous planes, providing different views of a geologic
structure with much higher resolution than is available with traditional
2-D seismic survey techniques.  Unlike 2-D seismic surveys, 3-D seismic
surveys require much larger acquisition systems with at least 480 recording
channels.  Moreover, large 3-D surveys increasingly requested by customers
may require 1,500 or more recording channels.  As a result of the more
subtle and complex geologic structures now being explored, 3-D seismic
surveys utilizing  state-of-the-art data acquisition systems increasingly
are conducted in the exploration stage to provide more extensive

                                                                  Page 3
information regarding subsurface geology.  In addition, 3-D surveys are
increasingly used to delineate locations for drilling development wells in
producing basins, as well as for reservoir management activities.

The Company believes that the growth in the use of 3-D seismic surveys will
continue, and that this trend is primarily attributable to:  (i) the
availability of improved technology capable of providing higher quality
data at a lower cost; (ii) the increased acceptance and interest by the
domestic energy industry of 3-D seismic techniques as a viable risk
management tool; and (iii) the success and increased use of 3-D seismic
surveys for field development and reservoir management applications in
addition to exploration activities.

                                RISK FACTORS

In addition to the other information set forth in this Prospectus, the
following factors should be carefully reviewed and considered in evaluating
the Company and this offering.

Dependence Upon Energy Industry Spending

Demand for the Company's services depends upon the level of capital
expenditures by oil and gas companies for exploration, production,
development, and field management activities.  These activities depend in
part on oil and gas prices, expectations about future prices, the cost of
exploring for, producing, and delivering oil and gas, the sale and
expiration dates of leases in the United States, the discovery rate of new
oil and gas reserves in land areas, local and international political,
regulatory, and economic conditions, and the ability of oil and gas
companies to obtain capital.  In addition, a decrease in oil and gas
expenditures could result from such factors as unfavorable tax and other
legislation or uncertainty concerning national energy policies.  The oil
and gas energy has been a cyclical business.  The outlook for domestic 3-D
data acquisition services remains positive at this time due to the
capability of this technology to provide higher quality data at a lower
cost, the increased acceptance of 3-D seismic techniques as a viable risk
management tool, and the increased success rates using 3-D surveys for
exploration and development activities.  The improved cost effectiveness
gained from the data acquisition and processing of 3-D surveys has resulted
in increased profits for the U.S. operations of the major and independent
oil and gas companies.  With these cost advantages and the uncertainty of
foreign operators, many of the major U.S. energy companies are increasing
participation in the domestic oil and gas industry.  However, no assurance 

                                                                  Page 6
can be given that current levels of oil and gas activities will be maintained 
or that demand for the Company's services will reflect the level of such
activities.  Decreases in oil and gas activities could have a significant
adverse effect upon the demand for the Company's services and the Company's
results of operations.
   
Risks of Operations

TGC's geophysical division had a small profit before interest and taxes in
1995 and was below expectations.  The 29% increase in revenues for 1995
when compared to 1994 can be attributed to a full year's operation of a
second seismic crew which commenced operations in the 1994 third quarter
when the Company's Sercel 368/348 data acquisition system was placed into
service.  In spite of this revenue increase, profit margins in 1995
decreased substantially due to unusually poor summer weather in the
Mid-Continent region and because several large contracts were canceled by
clients due to lease problems on their 3-D areas of interest, resulting in
interruption of the Company's planned data acquisition schedule.  In
addition, financial results were negatively impacted by a significant
increase in non-cash charges for depreciation ($800,796 for 1995 as
compared to $393,579 for 1994) as a result of the Company's capital
expansion program in the 1994 third quarter.  Revenues from continuing 
operations were $9,339,970 for the year ended December 31, 1996, compared
with revenues from continuing operations of $7,543,240 for the year
ended December 31, 1995.  Net income from continuing operations before
dividend requirements on preferred stock was $388,699 for the year
ended December 31, 1996.  The net loss from continuing operations was 
$24,086 for the year ended December 31, 1995.  EBITDA from continuing
operations was $1,267,527 or $.19 per common share and $829,358 or
$.14 per common share for the twelve months ended December 31, 1996, 
and 1995, respectively.  The increase in revenue was the result of a 
diversified backlog that included seismic surveys with higher contract 
prices in 1996 and the addition of state-of-the-art recording equipment 
in the second half of 1996.  Revenues from continuing operations for the
three months ended March 31, 1997, were $2,323,320 compared with revenues
from continuing operations of $2,234,672 for the same period of the prior
year.  TGC Industries, Inc. ("TGC") reported a loss from continuing
operations, after the dividend requirement on preferred stock, of 
$154,737 for the three months ended March 31, 1997.  This compares with 
income from continuing operations of $205,355 for the same period of 1996.  
This loss in the first quarter of 1997 was primarily the result of the 
Company's Eagle Crew No. 2 being immobilized on January 1, 1997, and 
suffering equipment losses in the California floods.  TGC was successful 
in securing replacement equipment and the crew returned to work at the end 
of February.  The other income of $417,033 was principally net insurance 
proceeds received for damaged and lost equipment and business interruption.  
Loss per common share from continuing operations, after dividend requirements 
on preferred stock, was $.02 for the first quarter of 1997, compared with 
income from continuing operations of $.03 for the same period of 1996.  See
"Management's Discussion and Analysis of Financial Condition and Results
of Operations."

Public Market for Securities

Warrants

Effective November 20, 1996, the Warrants are tradable on the NASDAQ SmallCap
Market under the symbol "TGCIW."  To date, however, a market has not developed 
in the Company's Warrants.  No assurance can be given that a market will 
develop or that a holder will be able to liquidate such holder's Warrants.
    

Preferred Stock

Effective November 20, 1996, the Preferred Stock began trading on the NASDAQ
SmallCap Market under the symbol "TGCIP."  The number of shareholders of 
record of the Preferred Stock is 95 as of April 21, 1997; however, 
the Company believes that there is a greater number of beneficial owners.  
Although the Company has two market makers for its Preferred Stock, trading 
in shares of the Preferred Stock is extremely light.  As a result, no 
assurance can be given as to the ability of a holder to readily liquidate 
such holder's shares of Preferred Stock in the Company.  

                                                                  Page 8


Common Stock

The Company's Common Stock has been traded under the symbol "TGCI" since
October 31, 1986.  From October 31, 1986 to September 22, 1994, the stock
traded in the over-the-counter market with quotations available in the
National Daily Quotation Source's "Pink Sheets" or on the "OTC Bulletin
Board" of the National Association of Securities Dealers.  Effective
September 25, 1994, TGC's Common Stock began trading on the NASDAQ SmallCap
Market under the same symbol "TGCI".  The number of shareholders of record
of TGC's Common Stock as of April 21, 1997 was 433.  The Company believes
that there is a significantly greater number of beneficial owners of its
Common Stock.  Although the Company has two market makers for its Common 
Stock, trading in shares of the Common Stock is extremely light.  As a 
result, no assurance can be given as to the ability of a holder to readily 
liquidate such holder's shares of Common Stock in the Company.  The Company
has never paid dividends on its Common Stock and has no plans to do so in
the future.     

Competition   

The land-based seismic data acquisition business is highly competitive. 
The Company believes that it has approximately 20 competitors in the United
States.  Competitive factors include price, crew experience, equipment
availability, technological expertise, and reputation for dependability. 
Certain of the Company's major competitors operate more data acquisition
crews than the Company, provide integrated data acquisition, processing and
interpretation services, have substantially greater revenues than the
Company, and are subsidiaries or divisions of major industrial enterprises
having far greater financial and other resources than the Company and more
extensive relationships with major integrated and multinational oil and gas
companies.  Such resources enable these competitors to maintain
state-of-the-art technology and certain other advantages relating to costs
that may provide them with an advantage over the Company in bidding for
contracts.  In addition, certain competitors of the Company take an
economic interest in oil and gas exploration and development projects for
which they perform services for their customers.  There can be no assurance
that the Company will be able to compete successfully against its

                                                                  Page 9
competitors for contracts to conduct seismic surveys.  See "Business of the
Company."

Capital Intensive Business; Rapid Obsolescence of Technology

The Company competes in a capital intensive industry.  The development of
seismic data acquisition equipment has been characterized by rapid
technological advancements in recent years and the company expects this
trend to continue.  There can be no assurance that manufacturers of seismic
equipment will not develop new systems that have competitive advantages
over systems now in use that could either render the Company's current
equipment obsolete or require the Company to make significant capital
expenditures to maintain its competitive position.  The Company's strategy
is to upgrade its data acquisition systems as often as necessary to
maintain its competitive position.  However, to do so may require large
expenditures of capital which the Company may be unable to accomplish.  See
"Business of the Company."

   
Operating Risks; Weather

The Company's crews often conduct operations in extreme weather, in
difficult terrain that is not easily accessible, and under other hazardous
conditions.  Accordingly, its operations are subject to risks of injury to
personnel and loss of equipment.  As a result, low productivity resulting
from weather interruptions, equipment failures, or other causes, such as
fires and accidental explosions resulting from the handling of equipment
and supplies, can result in significant operating losses.  In addition,
while the Company has insurance policies that protect it against
liabilities that may be incurred in the ordinary course of its business,
the Company is unable to insure fully against all possible loss or
liability.  See "Business of the Company -- Operating Conditions" and
"Management's Discussion and Analysis of Financial Condition and Results
of Operations."
    

Hazardous Operations

The Company's geophysical services business is subject to certain hazards,
including damage to equipment and injury to persons from explosives used in
land seismic operations.  The Company carries insurance on its equipment
and personnel in amounts which it considers adequate.  

                                                                  Page 10

Classification of the Board of Directors

The Company's Articles of Incorporation and Bylaws provide authorization
for dividing the Board of Directors into three separate classes having
staggered terms so that only one-third of the total number of Directors is
up for election at each annual meeting of the shareholders of the Company. 
The Company's Articles of Incorporation also provide that the provision
authorizing such a classification of the Board of Directors may not be
amended, altered, changed or repealed in any respect unless such action is
approved by the affirmative vote of the holders of eighty percent (80%) or
more of the issued and outstanding shares at a meeting called for such
purpose.  At the present time, the Company does not anticipate that a
classification of the Board of Directors into three separate classes with
each class having a staggered term, as provided above, will be placed into
effect.  See "Description of Securities."

Reliance on Key Personnel

The Company's operations are dependent on the efforts of its Vice-Chairman
and Chief Executive Officer, Robert Campbell and its President, Wayne
Whitener.  If any of these key persons becomes unable to continue in his
present role, or if the Company is unable to attract and retain other
skilled employees, the Company's business could be adversely affected.

Dependence on Major Customers

During the fiscal year ended December 31, 1996, three customers accounted 
for twenty percent (20%), fifteen percent (15%), and thirteen percent 
(13%) of the Company's revenue, respectively.  The loss or significant 
reduction of business from any of these customers may have a material 
adverse effect on the Company.  See "Business of the Company."

Environmental Regulations

Many of the Company's operations are affected by federal, state, and local

                                                                  Page 11
environmental regulations that could potentially be interrupted or
terminated on the basis of environmental or other considerations. 
Moreover, the Company is potentially subject to significant financial
penalties if it violates such regulations.  Attempt at compliance with such
regulations may affect the Company's operations and may necessitate
significant capital outlays.  See "Business of the Company."

Potential Increase In Shares of Common Stock Outstanding
   
As of April 21, 1997, there were 6,315,738 shares of the Company's Common
Stock outstanding.  Certain Warrants of TGC are exercisable for the
purchase of one share of Common Stock at $.375 per share of Common Stock, 
and an additional 737,174 shares of the Company's Common Stock are issuable
upon the exercise of such Warrants, assuming all outstanding Warrants are
exercised.  Additional warrants of TGC are exercisable at $.80 per share of
Common Stock.  An additional 150,000 shares of Common Stock are issuable
upon the exercise of such warrants.
    

The Series C 8% Convertible Exchangeable Preferred Stock at $5.00 per share
is convertible into Common Stock of the Company at the initial conversion
price per share of Common Stock of $.75, until July 1, 1998.  An additional
7,659,000 shares of the Company's Common Stock are issuable upon the
conversion of the Preferred Stock offered hereby, or, if exchanged by the
Company, the 8% Subordinated Convertible Debentures, Series A, assuming
conversion at the lowest conversion price per share of $0.75 per share of
Common Stock. 

   
In addition, shares of the Company's Common Stock are reserved for issuance
upon exercise of outstanding stock options under the Company's Incentive
and Nonqualified Stock Option Plan.  An additional 44,668 shares are
reserved for issuance upon exercise of outstanding stock options under the
Company's 1986 Stock Option Plan and an additional 493,000 shares are
reserved for issuance upon exercise of outstanding stock options under the
Company's 1993 Stock Option Plan.  Such shares may, in the future, be
issued and become available for sale in the public market.  See "Market for
the Company's Common Stock and Related Stockholder Matters."   
    
                                                                  Page 12

Future Sales of Outstanding Shares of Common Stock
   
Future sales of shares of Common Stock could adversely affect the
prevailing market price of the Company's Common Stock.  As of 
April 21, 1997, there were 6,315,738 shares of the Company's 
Common Stock outstanding.  Of such shares, 3,068,750 shares of 
Common Stock were issued in private placements in July and August, 
1993, and an additional 1,530,000 shares of Common Stock were issued 
pursuant to conversions of the Company's Series A and B Preferred 
Stock in July, 1994 and may be sold into the public market under 
Rule 144.  
    

No prediction can be made as to the effect, if any, that market sales of
shares of Common Stock or the availability of such shares for sale will
have on the market prices prevailing from time to time.  Nevertheless, the
possibility that substantial amounts of Common Stock may be sold in the
public market may adversely affect prevailing market prices for the Common
Stock and could impair the Company's ability to raise capital through the
sale of its equity securities.  See "Description of Securities."


                               USE OF PROCEEDS

Certain warrants of the Company are exercisable for $.375 per share.  The
Company will receive up to $276,440.25 if all of the holders of such
warrants exercise the warrants.  Certain other warrants are exercisable at
$.80 per share.  The Company will receive $120,000.00 if the holders of
such warrants exercise such warrants.  The Company intends to use any
proceeds received from the exercise of the warrants for working capital. 
The issuance of shares of Common Stock offered hereby upon conversion of
the outstanding shares of Preferred Stock  will not result in any proceeds
being received by the Company.  In addition, the exchange, if any, of
Debentures for Preferred Stock will not result in any proceeds being

                           BUSINESS OF THE COMPANY
   
TGC Industries, Inc., a Texas corporation (the "Company" or "TGC"), was
formed in April, 1980, as a wholly-owned subsidiary of Supreme Industries,
Inc., formerly ESI Industries, Inc., ("Supreme"), which acquired certain
equipment, instruments and related supplies of Tidelands Geophysical Co.,
Inc. ("Tidelands"), a Houston-based corporation which had been organized in
1967 and was engaged in the business of conducting seismic, gravity, and
magnetic surveys under contracts to companies in the exploration for oil
and gas.  In July, 1986, Tidelands' name was changed to TGC Industries,
Inc.  On June 30, 1986, the Board of Directors of Supreme and TGC approved
a spin-off whereby substantially all of the shares of TGC owned by Supreme
were distributed as a stock dividend to Supreme security holders.  On July
30, 1993, TGC acquired, through a wholly-owned subsidiary, Chase Packaging
Corporation ("Chase"), a specialty packaging business, principally
supplying products to the agricultural industry, through the purchase of
certain assets of the Chase Packaging division of Union Camp Corporation. 
On June 24, 1996, the Board of Directors of TGC approved the spin-off of
Chase effective July 31, 1996 whereby all of the shares of Chase owned by 
TGC were distributed as a stock dividend to the shareholders of TGC Common 
Stock and, on an as if converted basis, TGC Preferred Stock.  The record 
date for the spin-off was July 15, 1996 for the Common Stock and July 31, 
1996 for the Preferred Stock; however, the TGC Common Stock and Preferred 
Stock traded with "due bills" from the record date through the distribution 
date of the Chase Common Stock.  The distribution occurred on March 7, 1997.
    
Since its formation TGC has engaged in the domestic geophysical services

                                                                  Page 14
business, principally through conducting seismic surveys and to a lesser
extent through sales of gravity information from the Company's Data Bank to
companies engaged in the exploration for oil and gas in the United States.  
Geophysics is the study of the structure and composition of the earth's
interior and involves the measuring and interpretation of the earth's
properties with appropriate instruments.  Such studies are generally
conducted by means of surveys performed by field crews employing seismic,
gravity, or magnetic instruments to acquire data which is then interpreted
by various means to obtain useful information for oil and gas companies. 
The two survey techniques used by the Company in acquiring geophysical data
are seismic and gravity.  Land seismic surveys are the Company's principal
method of data acquisition and are by far the most widely used geophysical
technique.  The Company's seismic crew uses dynamite as the primary energy
source for such surveys. The Company has also developed three-dimensional
("3-D") recording capabilities that give the Company's crews the ability to
acquire a very dense grid of seismic data over a precisely defined area. 
The greater precision and improved subsurface resolution obtainable from
3-D seismic data have enabled energy companies in the U.S. to better
evaluate important subsurface features.

Business Strategy

The Company's objective is to become one of the leading providers of
land-based 3-D seismic acquisition services to the oil and gas industry in
the United States.  The Company intends to reach this objective through the
implementation of business strategies which include:

Upgrading its operation to state-of-the-art data acquisition systems -- 
In July, 1996, the Company purchased an Opseis Eagle 24-BIT 1500 channel 
recording system, cables and geophones for approximately $2,900,000, using 
$2,000,000 from proceeds from the Company's preferred stock private 
placement, a $750,000 equipment loan, and funds from internal cash flow.  
In late November 1996, the Company purchased a second 1000 channel Eagle 
system using the proceeds and trade-in from TGC's two older systems along 
with equipment financing of $855,000 and internal cash flow.  In February 
1997, TGC purchased an additional 500 channels utilizing equipment financing 
of $796,960.  At the present time, TGC is operating two Eagle 1500 channel 
crews.  The greater precision and improved subsurface resolution obtainable 
from 3-D seismic data have enabled energy companies in the U.S. to better 
evaluate important subsurface features.  The processing and interpretation 
of seismic data acquired by TGC are transmitted by the Company to data 
processing centers (not owned or operated by the Company) designated by the 
clients for processing.  
                                                                  Page 15

Optimizing equipment utilization -- The Company will seek to optimize
equipment utilization by relocating data acquisition systems among regions
to respond to regional and seasonal demand patterns.

Capitalizing on the strong reputation of the Company and its key executives
- -- TGC is an old-line, well respected seismic survey company with a
reputation for providing high quality seismic services to a broad range of
domestic exploration companies.  The Company plans to aggressively
capitalize on these factors.

Expanding operations through strategic acquisitions -- The Company will
seek to acquire other land-based seismic data acquisition businesses that
complement the Company's geographic market coverage and further the
Company's strategy for growth.  TGC periodically evaluates opportunities to
acquire businesses and assets; however, the Company does not have any
current understanding, arrangement, or agreement to acquire any such
businesses or assets.


No assurance can be given that the Company's strategy will be successful.
See "Risk Factors" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations".

Seismic Technology

Seismic data is acquired with the use of an energy source such as dynamite. 
The energy sources are discharged at or below the earth's surface,
producing acoustic waves which travel toward the center of the earth and
are reflected back to the surface depending upon the variations in the
underlying rock layers.  The reflected acoustic waves are detected by
sound-sensitive devices called "geophones," which are situated at intervals
along specified paths at varying distances from the energy source. 
Specialized seismic processing systems enhance recorded signals by reducing
distortion and improving resolution.  Seismic data, once recorded, is
processed using sophisticated computer software programs and arranged to
produce an image of the earth's substructure.  By interpreting seismic
data, geophysicists are able to create detailed maps of either prospective
drilling areas or of known oil and gas reservoirs.

                                                                  Page 16

Seismic Data Acquisition Services

TGC is engaged in land-based seismic data acquisition on a contract basis
for its customers and not for its own account.  When the Company is asked
to formulate a proposal to acquire seismic data on a customer's behalf, the
Company's geophysicists work with the customer in designing the
specifications of the proposed survey and, once the specifications are
agreed upon, the survey is taken to the field where one or more of the
Company's crews commence the process of acquiring data.

A seismic crew typically consists of permitting agents who secure
permission to enter a landowner's property, surveyors who mark the
locations for the placement of geophones and other equipment, general
laborers who place and move the geophones and other equipment, a drill crew
to drill holes and shooters to detonate the dynamite, and an observer who
operates the central electronics unit and controls the recording of the
seismic data.  A fully staffed 3-D seismic crew in the United States
typically has from 20 to 50 personnel conducting 3-D seismic surveys,
depending upon the size and nature of the survey required by the customer. 
Vehicles assigned to each crew consist of a recording truck, two or more
cable and geophone trucks, a dynamite truck and several personnel vehicles
with off-road capability.
   
The Company's crews are equipped with a minimum of 1,500 channel seismic
recording instruments, geophones and a variety of other seismic equipment. 
The Company believes that its customers will increasingly demand 3-D
seismic surveys.
    

The Company will seek to optimize equipment utilization by relocating data
acquisition systems among regions to respond to regional and seasonal
demand patterns. The following is a summary of the Company's current
technological seismic equipment:

                  Existing Capabilities and Crew Locations

                                      
                                  Crew 310

                                                                  Page 17

   This crew was recently equipped with an OPSEIS 24-BIT EAGLE Recording
   System capable of recording 1500 channels of seismic data at a 2MS
   sample rate.  This crew is State-of-the-Art and allows for diverse and
   cost effective 3-D operation.  Most of this crew's work has been in the
   Gulf Coast and Mid-Continent areas.  The primary clients for this crew
   are major and large to mid-sized independent companies.

                                  Crew 330
   
   This crew was recently equipped with an OPSEIS 24-BIT EAGLE Recording
   System capable of recording 1500 channels of seismic data at a 2MS
   sample rate.  The flexibility of this crew to overcome logistical 
   problems in difficult areas is a major plus in the acquisition of 
   3-D programs.  In the past, this crew has been working mainly in the 
   state of California for independent oil companies.  This crew is 
   currently working in Texas.
    

Seismic Data Processing

The processing of seismic data involves the conversion of such data, by
means of sophisticated computer software designed for this purpose, into
graphic representations of cross-sections of the earth's subsurface.
Because of the specialized computer technology required, the digital
seismic tapes acquired by the Company from its digital seismic surveys are
transmitted by the Company to data processing centers (not owned or
operated by the Company) designated by the customers for processing.

The Company's Data Bank contains gravity data and, to a lesser extent,
magnetic data from many of the major oil and gas producing areas located
within the United States.  The Company does not have a seismic data bank. 
Data Bank information has been amassed through participatory surveys as
well as speculative surveys funded by the Company alone.  All data and
interpretations may be licensed to customers at a fraction of the cost of
newly-acquired data.  At the present time, the company is experiencing low
sales in this area.

Operating Conditions

                                                                  Page 18

The Company's seismic data acquisition operations historically have been
subject to seasonal fluctuations, with the greatest volume of data
acquisition occurring during the summer and fall in the northern
hemisphere.  The Company may conduct operations year round with fewer days
of down-time caused by inclement weather by working during the favorable
operating seasons of different regions.  The Company believes that by
increasing the geographical scope of its operations, the impact on the
Company of seasonal fluctuations may be reduced.

Marketing and Customers

 I.   Marketing -- The Company's services traditionally have been marketed
      by the principal executive officers and marketing representatives.

II.   Contracts -- The Company provides its services to customers pursuant
      to contracts the terms of which are occasionally varied or modified
      by mutual consent.  In many instances, such contracts are cancelable
      by the customer on short notice without penalty.  Contracts are
      obtained by the Company either through competitive bidding, in
      response to invitations for bids, or by direct negotiation with a
      prospective customer.

Most frequently, customers invite bidders to provide quotations on the cost 
to gather seismic data over a specified region within a specified period of 
time.  Some customers, primarily large oil companies, require at least
three bids in order to award a contract.  Contracts are awarded primarily
on the basis of price, crew experience and equipment technology and
reputation for dependability.  

Contract terms, whether bid or negotiated, generally provide for payment by 
the customer on either a "turnkey" or a "term" basis or on a combination of 
both methods.  Under the turnkey method, payments for data acquisition 
services are based upon a fixed fee for each unit of data collected, and
the Company bears substantially all of the risk of business interruption
due to inclement weather and other hazards.  Term contracts, on the other
hand, provide for payment based on agreed rates per unit of time, which

                                                                  Page 19
may be expressed in periods ranging from days to months, and most of the
risk of business interruption (except for interruptions caused by failure
of the Company's equipment) is borne by the customer.  When a combination
of turnkey and term methods is used, the risk of business interruption is 
shared in an agreed percentage by the Company and the customer.  In each 
case, progress payments are usually required unless it is anticipated that 
the job will be completed in less than 30 days.  The majority of the 
Company's recent contracts for data acquisition have been on a turnkey
basis.

The Company's contracts specify that the seismic data acquired by the 
Company belongs to the Company's customer, and the Company does not acquire 
any seismic data for its own account.  All of the customer's information is 
maintained in confidence.

III.  Customers -- The Company's customers include and have included a
      number of major oil companies as well as many smaller, independent oil
      and gas operators.

 A large portion of the net sales of the Company in any period may be
 attributable to a limited number of customers, even though the mix of
 customers changes over time as contracts are awarded and completed.  The
 Company has a number of customers for which, over the years, services have
 been repeatedly provided.

IV.   Safety Program -- Certain of the Company's customers require, as a
      condition of awarding contracts, that a safety program designed to
      reduce the hazards associated with the seismic data acquisition
      business be in place.
   
V.   Backlog -- At March 1, 1997, the Company's crews are under contract
     through the end of current year.  The majority of such contracts
     consist of written contracts or commitments; however, contracts for 
     services are occasionally varied or modified by mutual consent and, 
     in many instances, are cancelable by the customer on short notice 

                                                             Page 20

     without penalty.  Consequently, the Company's backlog as of any 
     particular date may not be indicative of the Company's actual 
     operating results for any succeeding fiscal period.  Subject to the 
     foregoing, the Company anticipates that substantially all the 
     contracts and commitments included in backlog at March 1, 1997 will 
     be completed prior to the end of 1997.
    

As a service business, the Company's domestic geophysical services business
is not dependent upon the supply of raw materials or any other products,
and, therefore, the Company does not have arrangements with any raw
material suppliers, other than dynamite, which the Geophysical operations
obtains from several different suppliers.

   
The Company utilizes two seismic crews to perform its geophysical services
and, in any given period, these crews may generate a significant portion of



their respective revenues from one or more customers.  The present client
base consists of major oil companies and mid-size to small independent oil
and gas producers.  With the recent addition of two EAGLE Systems, TGC, with
this new equipment and technology, should be able to expand its current
markets and clients.  For the year end December 31, 1995, the Company
generated twenty-one (21%) of its revenues from contracts with one customer
and twelve percent (12%) of its revenues from another customer.  For the year 
ended December 31, 1996, three customers accounted for twenty percent (20%), 
fifteen percent (15%) and thirteen percent (13%) of the Company's revenue, 
respectively.  Management does not believe that the Company has any other 
material customers at the present time.  The Company enters into a general
or master agreement with each of its customers for the provision of
geophysical services and a supplementary agreement (which becomes a part of
the general agreement) with respect to each particular job that the Company
performs for a customer.  Under the terms of such agreements, the Company
generally contracts to supply all personnel, transportation, and equipment
to perform seismic surveys for a given prospect for a fixed price plus
reimbursement for certain third party charges.  The Company generally bills
its customers on a progressive basis over the term of the contract.  The
Company is generally obligated to maintain insurance against injury or
damage to persons or equipment arising from the performance of its services
and to indemnify its customers against all claims and liability arising
therefrom.

                                                                  Page 21

Activity in the U.S. Geophysical Industry has increased with the success
and acceptance of 3-D surveys.  The improved cost effectiveness gained from
the data acquisition and processing of 3-D surveys has resulted in
increased profits for the U.S. operations of the major and independent oil
companies. With these cost advantages and the uncertainty of foreign
operations, many of the major U.S. oil companies are increasing
participation in the domestic oil industry.  Both crews are working in
the Gulf Coast area at this time.
    




Additionally, due to the recent acquisition of two state-of-the-art 
instruments by the Company, management believes that TGC should experience an 
increase in revenues and operating profits.  However, due to uncertainties 
related to weather, the potential for contract delay or cancellation, and 
the potential for fluctuations in oil and gas prices, there can be no 
assurances that such improvement in revenue and operating profits can be 
achieved.  

Regulation

Seismic data acquisition operations are subject to various laws and
regulations. Such laws and regulations govern various aspects of
operations, including the discharge of explosive materials into the
environment, requiring removal and cleanup of materials that may harm the
environment or otherwise relating to the protection of the environment,
access to private and governmental land to conduct seismic surveys and use
of local employees and suppliers by foreign contractors.  The Company
believes that it has conducted its operations in substantial compliance
with applicable environmental laws and regulations governing its
activities.

Employees

As of December 31, 1996, TGC employed approximately 85 people of whom 
three performed management and marketing functions, three performed 
administrative services or clerical functions, four were geophysicists 
or rendered engineering or other technical services and approximately 77 
were members of the Company's seismic crews or performed other operations.  
None of the Company's employees is represented by a
                                                                  Page 22
labor union or a direct or indirect party to a collective bargaining
agreement.  The Company believes it has good relations with its employees.


                           PROPERTY OF THE COMPANY

                          DESCRIPTION OF PROPERTY.

     The Company's headquarters are in leased facilities located in Plano, 
Texas from which it conducts all its current operations.  These facilities 
include 8,000 square feet of office and warehouse space and an outdoor storage 
area of approximately 10,000 square feet.  The monthly rent is $4,010.  This 
facility is used to house corporate offices and serves as the headquarters for 
the geophysical business. The Company is not responsible for insuring the 
facilities.  The condition of the Company's facilities is good and TGC 
management believes that these properties are suitable and adequate for 
the Company's foreseeable needs.
         
     In July, 1996, the Company retained the Portland, Oregon facility from 
the spin-off of the Company's wholly owned subsidiary, Chase Packaging 
Corporation.  The facility is 88,000 square feet of office and manufacturing 
space with outdoor resin silos and a parking lot.  Chase had previously 
acquired the facility when Chase purchased certain assets of Union Camp 
Corporation's packaging division in July, 1993. On March 18, 1997, TGC sold 
the Portland, Oregon facility for $2,430,000 and applied such proceeds in 
satisfaction of the mortgage indebtedness with respect to such facility 
and in satisfaction of a debt obligation owing by TGC to Chase to pay to 
Chase any such proceeds in excess of the amount of the mortgage indebtedness.


        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION 
                         AND RESULTS OF OPERATIONS


RESULTS OF OPERATIONS

Geophysical Operation (Continuing Operations)

Three Months Ended March 31, 1997 Compared to Three Months Ended 
March 31, 1996

TGC Industries, Inc. ("TGC") reported revenues from continuing operations for
the three months ended March 31, 1997, of $2,323,320 compared with revenues
from continuing operations of $2,234,672 for the same period of the prior
year.  TGC reported a loss from continuing operations, before the dividend
requirement on preferred stock, of $39,852 for the three months ended March
31, 1997.  This compares with income from continuing operations of $205,355
for the same period of 1996.  There were no preferred stock dividends
incurred in the first quarter of 1996. Loss per common share from continuing
operations, after dividend requirements on preferred stock, was $.02 for the
first quarter of 1997, compared with income from continuing operations of
$.03 for the same period of 1996.

On January 1, 1997, Eagle Crew No. 2 was immobilized and suffered equipment
losses in the California floods.  TGC was successful in securing replacement
equipment and the crew returned to work at the end of February.  These losses
were partially offset by insurance coverage and TGC experienced a nominal
loss in the first quarter of 1997.  The other income of $417,033 was
principally net insurance proceeds for business interruption and equipment
lost or damaged in the California floods.
   
Despite the weather related problems in the first quarter of 1997, management
believes that 1997 will be a record year for revenues and earnings.  TGC has
two state-of-the-art Eagle 1500 Channel crews and these crews are under
contract through the end of 1997.  The geophysical business continues to be
favorable and strong.  However, with the unpredictable nature of forecasting
weather, the potential for contract delay or cancellation and the potential
for fluctuations in oil and gas prices, no assurance can be given that
management's expectations can be achieved.

Common shares of Chase Packaging Corporation ("Chase") were distributed on
March 7, 1997 to TGC shareholders, thereby concluding the spin-off of Chase. 
The spin-off was effective July 31, 1996.  As a result, Chase has been
accounted for as a discontinued operation in the accompanying financial
statements.
    
Fiscal Year Ended December 31, 1996 Compared to Fiscal Year Ended 
December 31, 1995

     Revenues from continuing operations were $9,339,970 for the year ended 
December 31, 1996, compared with revenues from continuing operations of 
$7,543,240 for the year ended December 31, 1995.  Net income from 
continuing operations before dividend requirements on preferred stock 
was $388,699 for the year ended December 31, 1996. The net loss from 
continuing operations was $24,086 for the year ended December 31, 1995.  
EBITDA from continuing operations was $1,267,527 or $.19 per common 
share and $829,358 or $.14 per common share for the twelve months ended 
December 31, 1996, and 1995, respectively.  The increase in revenue 
was the result of a diversified backlog that included seismic surveys 
with higher contract prices in 1996 and the addition of state-of-the-art
recording equipment in the second half of 1996.

     With the 23.8% increase in revenue for 1996 when compared to 1995, 
TGC's cost of services, as a percentage of revenue, decreased from 89.6% 
in 1995 to 86.5% in 1996 due to improved operating efficiencies.  Selling, 
general and administrative expenses, as a percentage of revenues, decreased 
from 10% in 1995 to 8.7% in 1996.  Interest expense increased by $12,407 
in 1996 when compared to 1995 primarily as a result of financing of 
geophysical equipment.  Non-cash charges for depreciation were $813,718 
in 1996 as compared to $800,796 in 1995.

     The outlook for domestic 3-D data acquisition services remains 
positive at this time due to the capability of this technology to provide 
higher quality data at a lower cost, the increased acceptance of 3-D 
seismic techniques as a viable risk management tool and the increased 
success rates using 3-D surveys for exploration and development 
activities.  The improved cost effectiveness gained from the data 
acquisition and processing of 3-D surveys has resulted in increased 
profits for the U.S.operations of major and independent oil and gas 
companies.  With these cost advantages and the uncertainty of foreign 
operations, many of the major U.S. energy companies are increasing 
participation in the domestic oil and gas industry.  The Company 
currently has a backlog that extends into the 1997 third quarter 
and includes programs in the Gulf Coast and mid-continent regions.  
The backlog includes small and large surveys for major and 
independent oil and gas companies.

     In July of 1996, TGC purchased a 24-BIT Opseis Eagle recording 
system with 1,500 channels and also acquired support equipment 
(cables and geophones) for this system.  The equipment was delivered 
in late July and began producing revenues in early August.  This 
equipment replaced TGC's Sercel 368/348 system. The purchase of these 
assets will improve recording capacity and marketability of TGC's 
seismic services, enabling the Company to take advantage of the current 
favorable environment for domestic exploration.  TGC used $2,000,000 in 
proceeds from the July 1996 private placement of Series C 8% Convertible 
Exchangeable Preferred Stock ("Preferred Stock"), together with outside 
financing, to purchase this system and support equipment.  In late 
November 1996, the Company purchased a second 1000 channel Opseis Eagle 
System using the proceeds and trade-in from TGC's two older systems 
along with equipment financing of $855,000 and internal cash flow.  
In February 1997, TGC purchased an additional 500 channels utilizing 
equipment financing of $796,960.  At the present time, TGC is operating 
two Eagle 1500 channel crews.

     TGC outfitted the second Eagle crew in late November 1996, and 
moved it to California. On January 1, 1997, Eagle No. 2 was immobilized 
and suffered equipment losses in the California floods.  TGC has been 
successful in recovering its remote recording devices and partially 
recovered certain cables and geophones.  Management was successful 
in securing replacement equipment and returned Eagle No. 2 to work 
at the end of February 1997.  As a result, TGC was back in full 
production with two crews in March 1997.  Due to the adverse 
California weather problems and the yet to be confirmed proceeds 
from the Company's equipment and business interruption insurance 
policies, TGC may experience a nominal loss in the first quarter of 1997. 
Eagles No. 1 and No. 2 are under contract through August 1997.

     As a result of the expanding recording capabilities and the current 
backlog for the Company, Management anticipates improved revenues and 
profit margins beginning in the second quarter of 1997.  However, a degree 
of risk is inherent in the Company's operations, due to possible downtime 
from adverse weather conditions, the nature of the Company's turnkey 
contracts which are subject to the risk of delay or cancellation, and 
the potential for fluctuations in oil and gas prices.  With the 
unpredictable nature of forecasting weather, the potential for 
contract delay or cancellation, and the potential for fluctuations in 
oil and gas prices, no assurance can be given that Management's 
expectations can be achieved.
         
     At December 31, 1996, the Company had net operating loss carry forwards 
of approximately $3,900,000 available to offset future taxable income, which 
expires at various dates through 2011.


Fiscal Year Ended December 31, 1995 Compared to Fiscal Year 
Ended December 31, 1994

Revenues for the twelve months ended December 31, 1995 increased 29% to
$7,543,240 from the 1994 annual revenues of $5,867,351.  Operating income
(before interest expense and taxes) was $28,562 for the year ended December
31, 1995 compared to operating income before interest and taxes of $717,068
for the twelve months ended December 31, 1994. Interest expense for the
twelve months ended December 31, 1995 was $52,648 which was attributable to
the financing of equipment additions for seismic operations.

The 29% increase in revenues for 1995 when compared to 1994 can be
attributed to a full year's operation of a second seismic crew which
commenced operations in the 1994 third quarter when the Company's Sercel
368/348 data acquisition system was placed into service.  In spite of this
revenue increase, profit margins in 1995 decreased substantially when
compared to 1994 due to unusually poor summer weather in Texas and
Oklahoma.  Also, several contracts were canceled by clients due to lease

                                                                  Page 25
problems on their 3-D areas of interest, resulting in interruption of the
Company's planned data acquisition schedule.  The ability of TGC's two
crews to record large quantities of data in a short period of time, which
is essential for profitability, was limited by these various problems and
resulted in lower operating margins.  In addition, financial results were
negatively impacted by a significant increase in non-cash charges for
depreciation ($800,796 for 1995 as compared to $393,579 for 1994) as a
result of the Company's capital expansion program in the 1994 third
quarter.

The trend in oil and gas exploration for a number of years has been to
focus on the larger potential of oil and gas fields outside the United
States.  In the past two years more of the Company's clients became
familiar with 3-D surveys and have had discoveries of oil and gas in the
United States using 3-D data.  The result was an increase in domestic
exploration activity from which the Company benefitted in 1994 as one of
the few remaining domestic geophysical contractors.  In 1995, however, the
increased activity has attracted additional geophysical contractors,
primarily from Canada, to the U.S. market.  These additional contractors
created a competitive bidding environment, but with an increased number of
contracts available during 1995, the Company was able to maintain its
revenue base.  However, profit margins were depressed due to TGC's
geographic concentration in the Mid-Continent region which resulted in crew
operations being hampered by unusually poor weather in such region during
1995.  In addition, work slow downs due to contract cancellations (as
previously discussed) in the third quarter contributed to TGC's 1995 profit
margin decline.

                                                                  Page 26

Discontinued Operations

     Effective July 31, 1996, the Company spun-off its wholly owned 
subsidiary, Chase Packaging Corporation, formerly New Chase Corporation, 
to the holders of TGC Common Stock and Preferred Stock.  Prior to the 
spin-off, through various corporate transactions, TGC liquidated Chase 
Packaging Corporation ("Old Chase") with TGC receiving all of Old Chase's 
properties and liabilities in cancellation of Old Chase stock held by TGC.  
TGC then formed a new wholly owned subsidiary, New Chase Corporation, a 
Texas corporation, the name of which TGC subsequently changed to Chase 
Packaging Corporation ("Chase").  TGC transferred to Chase all of the 
properties and liabilities previously received by TGC as a result of the 
liquidation of Old Chase, except TGC retained the Portland, Oregon 
facility of Old Chase and canceled all inter-company debt owed by Old 
Chase to TGC. On March 18, 1997, TGC sold the Portland, Oregon facility 
for $2,430,000 and applied such proceeds in satisfaction of the mortgage 
indebtedness with respect to such facility and in satisfaction of a debt 
obligation owing by TGC to Chase to pay to Chase any such proceeds in 
excess of the amount of the mortgage indebtedness.

     TGC spun-off Chase to the holders of TGC's Common Stock, and, on 
an as-if-converted basis, to the holders of TGC's Preferred Stock, which 
was sold in the private placement previously discussed. The record date was 
July 15, 1996, and July 31, 1996, for the Common Stock and Preferred Stock 
respectively ("Record Date"); however, since the TGC Common Stock and 
Preferred Stock traded with "due bills" from the Record Date through the 
distribution date, which was March 7, 1997, ("Distribution Date"), the 
holders of TGC Common Stock and Preferred Stock as of the Distribution 
Date received the dividend distribution.  An additional 539,837 shares 
of Chase Common Stock are held in escrow and for distribution upon 
exercise, if any, of outstanding warrants and options of TGC.  On the 
Distribution Date, the holders of TGC Common Stock received one-half 
share of Chase Common Stock for each share of TGC Common Stock held, 
and the holders of TGC's Preferred Stock received Common Stock of 
Chase on the basis of one-half share of Chase for each share of TGC 
Common Stock as if the Preferred Stockholder converted.  The $5.00 
per share Preferred Stock is initially convertible at $.75 per share 
of TGC Common Stock through July 1, 1998.  As a result of the spin off, 
the operations of Chase Packaging have been accounted for as a 
discontinued operation in the accompanying financial statements.  
Loss from discontinued operations for the seven month period ended 
July 31, 1996, was $1,402,706.

FINANCIAL CONDITION

Geophysical Operation (Continuing Operations)

     Cash of $2,446,644 was provided by continuing operations for the 
twelve months ended December 31, 1996, compared with cash provided by 
continuing operations of $1,149,188 for the same period of the prior year.  
The funds generated in the first twelve months of 1996 were primarily 
attributable to net earnings before non-cash depreciation charges for 
the Company's geophysical operation and to funds from advance billings 
in excess of costs and estimated earnings on uncompleted geophysical 
contracts.  Cash used in investing activities for 1996 was primarily 
for additions to machinery and equipment for geophysical field operations.  
Cash provided by financing activities were from the net proceeds of the 
private placement of $4,938,847, and proceeds from issuance of debt of 
$125,813. These proceeds were offset by principal payments on debt 
obligation of $259,079 and a capital contribution to Chase Packaging 
of $2,716,403.  Included in accrued liabilities at December 31, 1996, 
were dividends payable in the amount of $230,070, to holders of the 
Company's Series C 8% Convertible Exchangeable Preferred Stock.  The 
dividend was paid January 2, 1997.

     Working capital deficit increased $1,156,846 to $1,285,529 from 
the December 31, 1995, balance of $128,683, primarily as a result of 
billing in excess of costs and estimated earnings on uncompleted 
contracts and debt incurred in the purchase of geophysical equipment. 
As a result, the Company's current ratio declined to .65 to 1.0 at 
December 31, 1996, as compared to .92 to 1.0 at December 31, 1995.  
Stockholders' equity increased to $3,017,306 at December 31, 1996, 
from the December 31, 1995, of $1,643,127 due primarily to proceeds 
from the private placement.

   
     In July of 1996, TGC closed the private placement of 8% 
Convertible Exchangeable Preferred Stock.  TGC's geophysical operation 
received approximately $2,000,000 from the private placement and utilized 
the proceeds, together with outside financing of $750,000 and internally 
generated funds, to purchase a state-of-the-art geophysical 1500 
channel recording system. The Company placed this system into service in 
early August 1996. In late November 1996, the Company purchased a second 
1000 channel system using sale proceeds and a trade-in from TGC's two 
older systems along with equipment financing of $855,000 and internal 
cash flow.  This system was placed into service in December 1996.  
In late February 1997, TGC purchased an additional 500 channels utilizing 
equipment financing of $796,960.  At the present time, TGC is operating 
two 1500 channel crews.  The expanded recording capabilities provided by 
these systems should increase revenue and profit margins thereby improving 
the Company's operating cash flow in 1997.  However, due to the potential 
downtime from contract delays or cancellations, the uncertainty of weather 
conditions, and the potential for fluctuations in oil and gas prices, no 
assurance can be given that the Company's liquidity will improve to levels 
anticipated by Management.
    

Cash of $168,881 was provided from continuing operations for the first three
months of 1997 compared with cash provided from continuing operations of
$336,456 for the first three months of 1996.  The funds generated in the
first three months of 1997 were primarily attributable to net earnings before
non-cash depreciation charges.  Cash used in investing activities for the
first three months of 1997 was primarily for additions to machinery and
equipment for geophysical field operations.

Working capital decreased $967,930 to ($2,253,459) from the December 31, 1996
balance of ($1,285,529) primarily as a result of decreases in cash and cash
equivalents, accounts receivable, and costs and estimated earnings in excess
of billings on uncompleted contracts.  These decreases were primarily caused
by weather related problems in the first quarter of 1997, and management
believes with the current contracts and expected increase in revenues, the
Company's working capital should improve in the second quarter.  The
Company's current ratio was .3 to 1 at March 31, 1997, compared with .6 to 1
at December 31, 1996.

   
In March of 1997, the Company financed the acquisition of equipment through
a capital lease in the amount of $876,656.  In addition, on March 18, 1997,
the Company sold Chase's Portland, Oregon facility for $2,430,000.  The
proceeds of the sale were applied in satisfaction of the mortgage
indebtedness with respect to such facility and the excess proceeds were
remitted to Chase in satisfaction of a debt obligation to Chase.
    

Stockholders' equity decreased $143,829 from the December 31, 1996 balance of
$3,017,306 to $2,873,477 at March 31, 1997.  The completion of the spin-off
of Chase on March 7, 1997, resulted in a decrease of $103,977 in
stockholders' equity.




Discontinued Operations

     As previously discussed, the operation of Chase Packaging has been 
accounted for as a discontinued operation in the accompanying financial 
statements due to the July 31, 1996, spin-off of Chase to TGC shareholders.  
As part of the Company's reorganization plan, TGC made a capital contribution 
of $2,716,403 to Chase.

Dividends are payable on the Company's Common Stock at the discretion of
the Board of Directors.  In light of the working capital needs of the
Company, it is unlikely that cash dividends will be declared and paid on
the Company's Common Stock in the foreseeable future.  

      SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following tabulation sets forth the names of those persons who are
known to Management to be the beneficial owners as of March 20, 1997, of
more than five percent of the Company's Common Stock or Preferred Stock. 
Such tabulation also sets forth the number of shares of the Company's
Common Stock or Preferred Stock beneficially owned as of March 20, 1997, by
all of the Company's directors (naming them), executive officers, and all
directors and officers of the Company as a group (without naming them). 
Persons having direct beneficial ownership of the Company's Common Stock or
Preferred Stock possess the sole voting and dispositive power in regard to
such stock.  The Preferred Stock is freely convertible into shares of
Common Stock at the conversion price per share of Common Stock of $0.75 if
converted prior to close of business on July 1, 1998, at the conversion
price per share of Common Stock of $1.25 if converted after July 1, 1998
but prior to close of business on July 1, 1999, and at the conversion price
per share of Common Stock of $2.00 thereafter.  Ownership of Preferred
Stock is deemed to be beneficial ownership of Common Stock at the
conversion price per share of $0.75 under Rule 13d-3(d)(1) promulgated
under the Securities Exchange Act of 1934.  As of March 20, 1997, there were
6,315,738 shares of Common Stock and 1,148,850 shares of Preferred Stock
outstanding.

The Company maintains Club memberships for certain of its executive
officers.  Although these memberships may be utilized from time-to-time for
non-business purposes, the costs attributable to non-business purposes were
not material. The Company believes that the aggregate amounts of such
personal benefits do not exceed 10% of cash compensation paid to any
individual in the table or, with respect to the group of all executive
officers, ten percent(10%) of the aggregate cash compensation paid to the
members of such group.  

401(k) Plan

In 1987, the Company implemented a 401(k) salary deferral plan (the
Plan) which covers all employees who have reached the age of 20-1/2 years
and have been employed by the Company for at least one year.  The covered
employees may elect to have an amount deducted from their wages for
investment in a retirement plan.  The Company has the option, at its
discretion, to make contributions to the Plan.  Effective January 1, 1990,
the Company determined in its discretion to make a matching contribution to
the Plan equal to 10% of the employees' contributions up to 6% of those
employees' compensation.  On July 24, 1991, to be effective August 5, 1991,
the Board of Directors increased the Company's matching contribution to the
Plan to fifty cents ($.50) for every one dollar ($1.00) of compensation a
participant defers under the Plan up to 6% of those employees'
compensation.  Beginning January 4, 1993, the Board of Directors
discontinued the matching contribution to the Plan.  Concurrently with the
acquisition of Chase Packaging, the Board of Directors reinstated
contributions to the 401(k) salary deferral plan.  The Company makes a
matching contribution to the Plan equal to the sum of seventy-five percent
(75%) of each Participant's salary reduction contributions to the Plan for

                                                                  Page 38
such Plan year which are not in excess of three percent (3%) of the
Participant's compensation for such Plan year, and fifty percent (50%) of
each Participant's salary reduction contributions to the Plan for such Plan
Year which are in excess of three percent (3%) of the Participant's
compensation but not in excess of eight percent (8%) of the Participant's
compensation for such Plan Year. The total amount of the Company's
contribution during 1996 for the two (2) executive officers of the Company
participating in the 401(k) Plan was as follows:  Robert J. Campbell -
$3,148.65 and Wayne A. Whitener -$2,945.78.


Stock Option Plans

   
1986 Incentive and Nonqualified Stock Option Plan

In 1986 the Company adopted the 1986 Incentive and Non-Qualified Stock
Option Plan (the "1986 Plan").  The term of the 1986 Plan was for a period
of ten years with the result that the 1986 Plan terminated on July 24, 1996.

The provisions which were contained in the 1986 Plan were comparable
to the provisions contained in the 1993 Plan (hereafter described) which
succeeded the 1986 Plan.  

Options granted under the 1986 Plan cover 44,668 shares which are
currently outstanding.  During 1996, 25,000 stock options were granted under
the 1986 Plan.  Any stock option outstanding as of the date of termination
of the 1986 Plan will remain outstanding until it is exercised, terminated,
or expires.
    
                                                                  Page 39

1993 Stock Option Plan

On June 3, 1993, the Company's Board of Directors approved and adopted the
Company's 1993 Stock Option Plan (the "1993 Stock Option Plan").  At the
1994 Annual Meeting, shareholders approved the 1993 Stock Option Plan.  The
following paragraphs summarize certain provisions of the 1993 Stock Option
Plan and are qualified in their entirety by reference thereto.      

The 1993 Stock Option Plan provides for the granting of options
(collectively, the "Options") to purchase shares of the Company's Common
Stock to certain key employees of the Company (and/or any of its
affiliates), and certain individuals who are not employees of the Company
but who from time-to-time provide substantial advice or other assistance or
services to the Company (and/or any of its affiliates).  The 1993 Stock
Option Plan authorizes the granting of options (both statutory and
non-statutory) to acquire up to 750,000 shares of Common Stock, subject to
certain adjustments described below, to be outstanding at any time. 
Subject to the foregoing, there is no limit on the absolute number of
awards that may be granted during the life of the 1993 Stock Option Plan. 
At the present time, there are approximately 66 employees of the Company,
including four officers of the Company (three of whom are also directors),
who, in management's opinion, would be considered eligible to receive
grants under the 1993 Stock Option Plan, although fewer employees may
actually receive grants.
                                                                  Page 40


Authority to administer the 1993 Stock Option Plan has been delegated to a
committee (the "Committee") of the Board of Directors.  Except as expressly
provided by the 1993 Stock Option Plan, the Committee has the authority, in
its discretion, to award Options and to determine the terms and conditions
(which need not be identical) of such Options, including the person to
whom, and the time or times at which, Options will be awarded, the number
of Options to be awarded to each such person, the exercise price of any
such Options, and the form, terms, and provisions of any agreement pursuant
to which such Options are awarded.  The 1993 Stock Option Plan also
provides that the Committee may be authorized by the Board of Directors to
make cash awards as specified by the Board of Directors to the holder of an
Option in connection with the exercise thereof.  

Subject to the limitations set forth below, the exercise price of the
shares of stock covered by each 1993 Option will be determined by the
Committee on the date of award.

Unless a holder's option agreement provides otherwise, the following
provisions will apply to exercise by the holder of his or her option:  No
options may be exercised during the first twelve months following grant. 
During the second year following the date of grant, options covering up to
one-third of the shares covered thereby may be exercised, and during the
third year following the date of grant, options covering up to two-thirds
of such shares may be exercised.  Thereafter, and until the options expire,
the optionee may exercise options covering all of the shares.  With regard
to approximately one-half of the options which have been granted, the
Grantee can exercise up to one-half of the number of shares covered by an
option during the first twelve months following the date of grant, and the
balance thereafter (with the latter being limited in some cases to
individual performance). Persons over sixty-five on the date of grant may
exercise options covering up to one-half of the shares during the first
year and thereafter may exercise all optioned shares. Subject to the
limitations just described, options may be exercised as to all or any part
of the shares covered thereby on one or more occasions, but, as a general
rule, options cannot be exercised as to less than one-hundred shares at any
one time.
                                                                  Page 41


The exercise price of the shares of stock covered by each incentive stock
option ("ISO"), within the meaning of Sec. 422 of the Internal Revenue Code
of 1986, as amended (the "Code"), will not be less than the fair market
value of stock on the date of award of such ISO except that an ISO may not
be awarded to any person who owns stock possessing more than ten percent
(10%) of the total combined voting power of all classes of stock of the
Company unless the exercise price is at least one hundred ten percent
(110%) of the fair market value of the stock at the time the ISO is awarded
and the ISO is not exercisable after the expiration of five years from the
date it is awarded. The exercise price of the shares of Common Stock
covered by each Option that is not an ISO will not be less than fifty
percent (50%) of the fair market value of the stock on the date of award.  

Payment for Common Stock issued upon the exercise of an Option may be made
in cash or with the consent of the Committee, in whole shares of Common
Stock owned by the holder of the Option for at least six months prior to
the date of exercise or, with the consent of the Committee, partly in cash
and partly in such shares of Common Stock.  If payment is made, in whole or
in part, with previously-owned shares of Common Stock, the Committee may
issue to such holder a new Option for a number of shares equal to the
number of shares delivered by such holder to pay the exercise price of the
previous Option having an exercise price equal to at least one-hundred
percent (100%) of the fair market value per share of the Common Stock on
the date of the exercise of the previous Option.  

The duration of each Option will be for such period as the Committee
determines at the time of award, but not for more than ten years from the
date of award in the case of an ISO. 

In the event of any change in the number of shares of Common Stock effected
without receipt of consideration therefor by the Company by reason of a
stock dividend, or split, combination, exchange of shares or other
recapitalization, merger, or otherwise, in which the Company is the
surviving Corporation, the aggregate number and class of reserved shares,
the number and class of shares subject to each outstanding Option, and the 

                                                                   Page 42
exercise price of each outstanding Option will be automatically adjusted to
reflect the effect thereon of such change.  Unless a holder's option
agreement provides otherwise, a dissolution or liquidation of the Company,
certain sales of all or substantially all of the assets of the Company,
certain mergers or consolidations in which the Company is not the surviving
corporation, or certain transactions in which another corporation becomes
the owner of fifty percent (50%) or more of the total combined voting power
of all classes of stock of the Company, will cause such holder's Options
then outstanding to terminate, but such holder may, immediately prior to
such transaction, exercise such options without regard to the period and
installments of exerciseability applicable pursuant to such holder's option
agreement.

The 1993 Stock Option Plan will terminate on June 3, 2003, or such earlier
date as the Board of Directors may determine.  Any stock option outstanding
at the termination date will remain outstanding until it has been
exercised, terminated, or has expired. The 1993 Stock Option Plan may be
terminated, modified, or amended by the Board of Directors at any time
without further shareholder approval, except that shareholder approval is
required for any amendment which:  (a) changes the number of shares of
Common Stock subject to the 1993 Stock Option Plan other than by adjustment
provisions provided therein,  (b) changes the designation of the class of
employees eligible to receive Options,  (c) decreases the price at which
ISO's may be granted, (d) removes the administration of the 1993 Stock
Option Plan from the Committee, or (e) without the consent of the affected
holder, causes the ISO's granted under the 1993 Stock Option Plan and
outstanding at such time that satisfied the requirements of Sec. 422 of the
Code no longer to satisfy such requirements.

   
During 1996 stock options of 590,000 were granted under the Company's 1993
Stock Option Plan to officers and employees of the Company, and certain
officers and employees of the Company's former subsidiary, Chase Packaging
Corporation.  Granted options covering 535,500 shares are outstanding at
December 31, 1996 under the 1993 Stock Option Plan.

Effective July 31, 1996, the Company's wholly-owned subsidiary, Chase
Packaging Corporation ("Chase"), was spun off to the Company's shareholders.
In view of this situation, and in order to provide the employees of both
Chase and the Company with the maximum period available under the tax laws
for exercising their options after a termination of employment, the 1993
Plan was amended to extend from thirty days to three months, the period
of time following termination of employment, during which the terminating
employee can exercise his or her option.
    
                                                                  Page 43  

  ISO's Exercised in 1996 and First Quarter 1997 by Officers of Company
   
No stock options were exercised by officers of the Company in 1996.

On January 7, 1997, options for shares of Common Stock at an exercise 
price of $1.00 and $.40, respectively, per share were exercised by Mr. 
Wayne A. Whitener, President of the Company.  The Company received
14,025 shares of its Common Stock at a market value of $1.6875 per
share as payment for the exercise of the options.

                        TRANSACTIONS WITH MANAGEMENT

On May 31, 1994 the holder of the 9% Convertible Subordinated Preferred
Stock elected to convert the Preferred Stock into 26,666 shares of TGC
Common Stock.  On July 2, 1994, 500,000 shares of Convertible Preferred
Stock held by certain affiliates of the Company were converted into
1,530,000 shares of the Company's Common Stock.  Pursuant to the terms
governing the Preferred Stock and based upon the Company having achieved a
trading price for its Common Stock of $1.60 per share for thirty
consecutive trading days, all holders of the Convertible Preferred Stock
elected to exercise their conversion privilege as of this date.

On July 28, 1995, 64,676 shares of Common Stock were contributed to the
Company by a Director of TGC Industries, Inc.  The Company included these
shares in its treasury stock account at $2.50 per share which represents
the fair market value of the Company's Common Stock on the date of the
transaction.

On July 31, 1995, certain executive officers and directors of the Company
exchanged $200,000 in short-term debt for Private Placement Units.  On
August 1, 1995,  4,874 Units were issued as payment of accrued interest on
this debt.

In the fourth quarter of 1995, certain executive officers and directors of
the Company made loans to the Company in the amount of $240,000 due to the
cash requirements of the Company at the time. Interest expense of $3,538.35
was accrued on these loans for this period. 

   
In 1996, the Company had outstanding Subordinated Notes payable in the
amount of $365,812 to certain executives, officers and directors of the
Company.  Interest expense of $18,579 was paid on this debt during 1996.
In July 1996, the Company exchanged this debt for 73,162 shares of Series C 
8% Convertible Exchangeable Preferred Stock in connection with the private
placement of such Preferred Stock in July, 1996.
    
                                                               Page 45
                          DESCRIPTION OF SECURITIES
   
The Company's Articles of Incorporation authorize 25,000,000 shares of
Common Stock with a par value of $.10 per share.  Each holder of Common
Stock is entitled to one vote per share held of record at each meeting of
the stockholders.  As of April 21, 1997, there were 6,315,738 shares of the
Company's Common Stock outstanding.  The Company is also authorized to
issue 4,000,000 shares of Preferred Stock with a par value of $1.00 per
share. The Board of Directors authorized the issuance of 1,250,000 shares
of Series C 8% Convertible Exchangeable Preferred Stock.  Each holder of
Preferred Stock is entitled to one vote per share held of record at each
meeting of the stockholders.  As of April 21, 1997, there were 1,148,850
shares of the Company's Preferred Stock outstanding.  The Preferred Stock
is convertible into shares of the Company's Common Stock and is convertible
at the conversion price per share in years one and two at $.75, year three
at $1.25, and thereafter at $2.00.  Dividends at the rate of 8% per annum
will accrue from the closing date and are payable, upon declaration by the
Board of Directors, semi-annually, commencing January 1, 1997.  The
Preferred Stock is exchangeable in whole by the Company, at its sole
option, into 8% Subordinated Convertible Debentures, Series A; provided
that the Company may not exercise such exchange option prior to January 1,
1998.
    
Warrants

The Company issued Warrants as a component of Units offered in a private
placement that closed in September, 1995.  As of July 31, 1996, there were
737,174 Warrants issued in connection with that private placement
outstanding.  Each Warrant is exercisable for the purchase of one share of
Common Stock for a period of 3 years from September 8, 1995 at $.375 per
share.  The Warrants are not callable or redeemable by the Company prior to
the end of the 3 year term.  If not exercised at the end of the 3 year
term, each Warrant certificate or certificates representing, immediately
before the end of their term, the right to purchase one share of Common
Stock will automatically convert into one-tenth of one share of Common 

                                                                  Page 46
Stock of the Company.  Fractional shares will not be issued upon the 
exercise of the Warrants.  In lieu thereof, a cash adjustment based on the
fair market value of the Common Stock on the date of exercise will be made.

The Company entered into a Warrant agreement with American Stock Transfer
and Trust Company, as the Warrant agent in favor of the Warrant holders,
which provides that the number of shares of Common Stock to be obtained
upon exercise of a warrant, and the exercise price, are subject to
adjustment (a) in the event of a stock dividend, split-up, sub-division,
combination, or reclassification of the Company's Common Stock, and (b) for
any capital reorganization or reclassification of the Common Stock of the
Company, any mergers or consolidations of the Company with another entity,
or the sale of substantially all of the assets of the Company.

Series C 8% Convertible Exchangeable Preferred Stock

The following summaries of certain provisions of the Series C 8%
Convertible Exchangeable Preferred Stock do not purport to be complete and
are subject to, and are qualified in their entirety by reference to all
provisions of the Statement of Resolution Establishing Series C 8%
Convertible Exchangeable Preferred Stock attached as Exhibit "A" hereto,
including the definitions therein of certain terms.

General

The Company is authorized to issue shares of preferred stock in series, and
in connection with such issuance, the Board of Directors of the Company is
authorized without a further vote of the shareholders to fix the rights and
qualifications, limitations or restrictions of any series of preferred
stock, including the number of shares constituting any such series and the
designation thereof, the voting rights, rights and terms of redemption,
dividend rights, liquidation preferences and the rights and terms of
conversion into shares of any other class or classes or any other series of
the same or any other class or classes of stock of the Company.  The Board
of Directors has resolved that 1,250,000 shares of the Company's
undesignated shares be designated as Series C 8% Convertible Exchangeable
Preferred Stock (the "Preferred Stock").  Prior to the offering of the 

                                                                  Page 47

designation of the Series C Preferred Stock, no series of preferred stock
was outstanding.  To the extent that all shares of the Preferred Stock are
not issued, the Board of Directors of the Company would have the authority,
without shareholder approval, to issue the remaining undesignated shares
 with voting, conversion, liquidation, dividend and other rights which
could be on a parity with the Preferred Stock.  In addition, future
issuances of additional shares of preferred stock could make it more
difficult for a third party to acquire a majority of the outstanding voting
stock of the Company and accordingly may be used as an anti-takeover
device.

The Company issued 1,150,350 shares of Series C 8% Convertible Exchangeable
Preferred Stock in connection with a private placement that closed in July,
1996.  The following is a description of the Preferred Stock which does not
purport to be complete and is subject to, and qualified in its entirety by
reference to, the Company's Articles of Incorporation, and the Statement of
Resolution Establishing Series C 8% Convertible Exchangeable Preferred
Stock (the "Statement of Resolution") filed with the Secretary of State of
Texas, which is attached as Exhibit "A" hereto.

Dividends

Holders of shares of the Preferred Stock will receive, when, as and if
declared by the Board of Directors of the Company, dividends at a rate of
eight percent (8%) per annum, payable semi-annually on January 1 and July 1
of each year, commencing January 1, 1997.  Dividends will be cumulative,
will accumulate from the date of original issuance and will be payable to
holders of record of the Preferred Stock as they appear on the books of the
Company on such respective dates, not exceeding 60 days preceding such
dividend payment date, as may be fixed by the Board of Directors of the
Company in advance of the payment of each particular dividend.

The Preferred Stock ranks senior to the Common Stock as to dividends and
upon liquidation.  Before any dividends (other than dividends payable in
Common Stock) on any class or series of stock of the Company ranking junior
to the Preferred Stock as to dividends or upon liquidation shall be
declared or paid or set apart for payment, the holders of shares of the 

                                                                  Page 48
Preferred Stock are entitled to receive cumulative cash dividends, but only
when and as declared by the Board of Directors, at the rate set forth
above.  No dividends can be declared on any class or series of stock
ranking on a parity with the Preferred Stock as to dividends in respect of
any dividend period unless there shall likewise be or have been declared on
the Preferred Stock like dividends for all semi-annual periods coinciding
with or ending before such semi-annual period ratably in proportion to the
respective annual dividend rates fixed therefor.  If the Company is in
default with respect to any dividends payable on its Preferred Stock, the
Company may not declare or pay or set apart for payment any dividends or
make any distribution in cash or other property on, or redeem, purchase or
otherwise acquire, any other class or series of stock ranking junior to the
Preferred Stock either as to dividends or upon liquidation.  Accruals of
dividends will not bear interest.
 
The amount of dividends payable per share for each dividend period shall be
computed by dividing the annual rate by two (2).  The amount of dividends
payable for the initial dividend period or any period shorter than a full
dividend period shall be computed on the basis of a 360-day year of 12
30-day months.

Conversion

The holders of Preferred Stock are entitled at any time to convert their
shares of Preferred Stock into shares of Common Stock at the following
conversion rates (subject to adjustment as described below):

(a)  prior to the close of business on July 1, 1998, at the conversion
     price per share of Common Stock of Seventy-Five Cents ($0.75);

(b)  after July 1, 1998, and prior to the close of business on July 1,
     1999, at the conversion price per share of Common Stock of One Dollar
     and Twenty-Five Cents ($1.25); and 

(c)  thereafter, at the conversion price per share of Common Stock of Two
     Dollars ($2.00).


                                                                  Page 49

Shares of Preferred Stock surrendered for conversion during the period from
the close of business on any record date for the payment of dividends on
such Preferred Stock to the opening of business on the corresponding
dividend payment date (except shares called for redemption during such
period) must be accompanied by payment of an amount equal to the dividend
payable on such shares on the corresponding dividend payment date
notwithstanding the conversion thereof or the Company's default in payment
of the dividend due on such dividend payment date.  A holder of Preferred
Stock on a dividend payment date will receive the dividend payable on such
Preferred Stock by the Company on such date, and the converting holder need
not include payment in the amount of such dividend upon surrender of shares
of Preferred Stock for conversion.

No fractional shares will be issued upon conversion and, in lieu thereof,
an adjustment in cash will be made based upon the last reported sale price
of the Common Stock (or if not available, the average of the closing bid
and asked prices) on the NASDAQ National Market System or SmallCap Market,
on the principal national securities exchange, or the over-the-counter
system where the Common Stock may then be traded, on the last business day
prior to the date of such conversion.

The conversion rate is subject to adjustment in certain events, including
(i) the issuance of capital stock of the Company as a dividend or a
distribution, (ii) subdivisions, combinations and reclassifications of the
Common Stock, and (iii) the distribution to all holders of Common Stock of
evidences of indebtedness of the Company or of assets (other than cash
dividends from retained earnings) or subscription rights to securities of
the Company.  Except in these cases, the conversion rate will not be
adjusted for the issuance of Common Stock.  The Company reserves the right
to make such increases in the conversion rate in addition to those required
by the foregoing provisions as the Company in its discretion shall
determine to be advisable in order that certain stock related distributions
hereafter made by the Company to its shareholders shall not be taxable.

Except as discussed above, no adjustment upon conversion will be made for
dividends on either the Preferred Stock or the Common Stock.


                                                                  Page 50
In case of any consolidation or merger of the Company with or into another
corporation or entity other than a consolidation or merger in which the
Company is the continuing corporation and which does not result in any
reclassification of or change in outstanding shares of Common Stock, or any
sale or transfer of all or substantially all the assets of the Company, the
holder of each share of Preferred Stock shall after such consolidation,
merger, sale or transfer have the right to convert such share of Preferred
Stock into the kind and amount of securities, cash and other property which
such holder would have been entitled to receive upon such consolidation,
merger, sale or transfer if the holder had held the Common Stock issuable
upon the conversion of such share of Preferred Stock immediately prior to
such consolidation, merger, sale or transfer.

Redemption at Option of the Company

Except for any redemption which the Company would be prohibited from
effecting under applicable law, and provided the shares of Preferred Stock
of a holder have not earlier been converted or exchanged in accordance with
the provisions of the Preferred Stock, the shares of Preferred Stock may be
redeemed by the Company, in whole or in part, at the option of the Company
upon written notice by the Company to the holders of Preferred Stock at any
time after July 1, 2000, in the event that the Preferred Stock of one or
more holders has not been converted or exchanged pursuant to the terms
hereof on or before such date.  The Company shall redeem each share of
Preferred Stock of such holders within thirty (30) days of the Company's
delivery of the above notice to such holders and such holders shall
surrender the certificate(s) representing such shares of Preferred Stock. 
For any partial redemptions the Company shall redeem shares in proportion
to the number of shares held by each holder.  The redemption amount shall
be $5.00 per share, plus in each case accrued and unpaid dividends thereon
to the date of payment of such amount (the total sum so payable on any such
redemption being herein referred to as the "redemption price"); provided,
however, that for any such redemption which is effected (i) on or after
July 1, 2001 but prior to July 1, 2002, a premium of ten percent (10%) of
the per share amount of such Preferred Stock shall be paid per share (i.e.
$0.50 per share of Preferred Stock), (ii) on or after July 1, 2002 but
prior to July 1, 2003, a premium of 20% per share (i.e. $1.00 per share);

                                                                  Page 51
(iii) on or after July 1, 2003 but prior to July 1, 2004, a premium of 30%
per share (i.e. $1.50 per share); (iv) on or after July 1, 2004 but prior
to July 1, 2005, a premium of 40% per share (i.e. $2.00 per share); and on
or after July 1, 2005 a premium of 50% per share (i.e. $2.50 per share).

Upon payment of such redemption price, the shares represented thereby shall
no longer be deemed outstanding, the right to receive dividends and
distributions shall cease to accrue on and after such date, and all rights
of the holder of the Preferred Stock as a shareholder of the Company shall
cease and terminate.

Exchange into Subordinated Convertible Debentures

The Preferred Stock is exchangeable in whole, but not in part, at the sole
option of the Company into the Company's 8% Subordinated Convertible
Debentures, Series A at an exchange rate of $5.00 principal amount of
Subordinated Debentures for each share of Preferred Stock; provided that
the Company may not exchange any shares of Preferred Stock unless all
cumulative dividends have been paid to the date of exchange.  The Company's
exchange option is further restricted by the terms of the Preferred Stock
which provide the Company may not exercise such exchange option prior to
January 1, 1998.  Furthermore, under the terms of the Preferred Stock:  (1)
the maturity date of the Convertible Debentures will be equal to the later
of July 1, 2000 or two years from the date of exchange of such Preferred
Stock, and (2) in the event of an exchange of Preferred Stock for
Convertible Debentures on or after July 1, 2001, the principal amount of
Debentures exchanged for each share of Preferred Stock shall include a
premium identical to the premium described above with respect to the
Company's exercise of its redemption option or after such date (e.g. for an
exchange on or after July 1, 2001 but prior to July 1, 2002, a premium of
ten percent (10%) of the principal amount of the Debentures per share (i.e.
a premium of $0.50 per share of Preferred Stock or a Convertible Debenture
in the principal amount of $5.50 per share of Preferred Stock.))

Under the terms of the Convertible Debentures, the Debentures will have a
maturity date equal to the later of July 1, 2000 or two years from the date
of exchange.  The Company shall send to each holder of Preferred Stock

                                                                  Page 52
notice of the exchange not less than 30 days nor more than 60 days prior to
the exchange date at the address shown on the books of the Company.  On and
after the date of exchange of Preferred Stock for Subordinated Debentures,
the Preferred Stock shall cease to accrue dividends, shall no longer be
deemed to be outstanding and shall represent only the right to receive the
Subordinated Debentures.

Voting Rights

The holders of the shares of Preferred Stock are entitled to one vote per
share of Preferred Stock held by them, to vote upon all matters which the
holders of shares of the Company's Common Stock shall have the right to
vote.  In all cases, as a matter of law, where the holders of shares of
Preferred Stock shall have the right to vote separately as a class, such
holders will also be entitled to one vote per share of Preferred Stock held
by them.

The affirmative vote or consent of the holders of at least two-thirds of
the outstanding shares of the Preferred Stock, voting as a class, will be
required to (i) authorize, create or issue, or increase the authorized or
issued amount of, shares of any class or series of stock ranking senior to
the Preferred Stock, either as to dividends or upon liquidation, or (ii)
amend, alter or repeal (whether by merger, consolidation or otherwise) any
provisions of the Company's Articles of Incorporation or of the Statement
of Resolution establishing this series of Preferred Stock so as to
materially and adversely affect the preferences, special rights or powers
of the Preferred Stock; provided, however, that any increase in the
authorized preferred stock or the creation and issuance of any other series
of preferred stock ranking on a parity with or junior to the Preferred
Stock shall not be deemed to materially and adversely affect such
preferences, special rights or powers.

Liquidation Rights

In the event of any liquidation, dissolution or winding-up of the Company,
whether voluntary or involuntary, before any payment or distribution of the
assets of the Company, or proceeds thereof (whether capital or surplus),

                                                                  Page 53
shall be made to or set apart for the holders of any class of stock of the
Company ranking junior to the Preferred Stock upon liquidation, the holders
of the Preferred Stock shall be entitled to receive $5.00 per share, plus
an amount equal to all dividends (whether or not earned or declared)
accrued and unpaid to the date of final distribution, but such holders
shall not be entitled to any further payment.  If, upon any liquidation,
dissolution or winding-up of the Company, the assets of the Company, or
proceeds thereof, distributable among the holders of shares of the
Preferred Stock and any other class or series of preferred stock ranking on
a parity with the Preferred Stock as to payments upon liquidation,
dissolution or winding-up shall be insufficient to pay in full the
preferential amount aforesaid, then such assets, or the proceeds thereof,
shall be distributed among such holders ratably in accordance with the
respective amounts that would be payable on such shares if all amounts
payable thereon were paid in full.  The voluntary sale, conveyance, lease,
exchange or transfer (for cash, shares of stock, securities or other
consideration) of all or substantially all the property or assets of the
Company to, or a consolidation or merger of the Company with, one or more
other corporations (whether or not the Company is the corporation surviving
such consolidation or merger) will not be deemed to be a liquidation,
dissolution or winding-up, voluntary or involuntary.

8% Subordinated Convertible Debentures, Series A

If the Company elects to exchange the Preferred Stock for the Company's 8%
Subordinated Convertible Debentures, Series A ("Subordinated
Debentures"),the Company will issue the Subordinated Debentures to all
holders of Preferred Stock.  The following summaries of certain provisions
of the Subordinated Debentures, do not purport to be complete and are
subject to, and are qualified in their entirety by reference to, all
provisions of the Form of Debenture Agreement and the Debenture attached as
Exhibit "B" hereto, including the definitions therein of certain terms.

General

The Subordinated Debentures will be unsecured, subordinated obligations of
the Company, limited to an aggregate principal amount equal to the

                                                                  Page 54
aggregate stated value of the Preferred Stock for which the Subordinated
Debentures are exchanged, and will mature on the later of July 1, 2000 or
two years from the date of exchange of Preferred Stock for Subordinated
Debentures.  The Company will pay interest on the Subordinated Debentures
semi-annually at 8% per annum, the same rate as paid on the Preferred
Stock.  Interest will be paid on the Subordinated Debentures to the persons
who are registered holders at the close of business on the 15th day of the
month next preceding the interest payment date.  Interest will be computed
on the basis of a 360-day year of 12 30-day months.  Principal and interest
will be payable and the Subordinated Debentures may be presented for
conversion, exchange or transfer at the principal office of the Company.

Conversion Rights

The holders of Subordinated Debentures will be entitled at any time on or
before the maturity thereof to convert the Subordinated Debentures into
Common Stock of the Company.  The initial conversion price of the
Debentures will be at the same conversion price in effect for the Preferred
Stock at the date of exchange of the Preferred Stock for Subordinated
Debentures.  Following the date of exchange, the terms of the Debentures
with respect to the conversion price and the adjustments to the conversion
price are identical, in all material respects, to such terms contained in
the Preferred Stock as described above.

Subordination

The payment of principal (and premium, if any) and interest on, the
Subordinated Debentures is subordinated in right of payment to the payment
of all Superior Indebtedness of the Company.  "Superior Indebtedness" is
defined as (a) Funded Debt, being all indebtedness of the Company having a
final maturity of more than one year, and all guarantees of indebtedness
extending more than one year, from its "date of origin" or which is
renewable or extendable at the option of the obligor for a period or
periods of more than one year from its date of origin, and all amounts due
under capitalized leases reflected on the balance sheets; and (b) Current
Debt, being all unsecured indebtedness for money borrowed, payable on
demand or having a maturity or not more than one year from the date of

                                                                  Page 55
determination (other than current maturities of Funded Debt) and not
extendable or renewable at the option of obligor.

The Company is not limited in the amount of Superior Indebtedness that may
be incurred and the Company may from time to time incur additional Superior
Indebtedness.  In addition, any subsidiary of the Company may incur
liabilities and have obligations to third parties.  The claims of such
third parties to the assets of such subsidiaries will be superior to those
of the Company as a shareholder and therefore the Subordinated Debentures
may be deemed to be effectively subordinated to the claims of such third
parties.

In the event of any payment or distribution of assets or securities of the
Company upon any liquidation, dissolution, winding-up or reorganization of
or similar proceeding relating to the Company, the payment of the principal
(and premium, if any) and interest on the Subordinated Debentures is to be
subordinated in right of payment to the prior payment in full of all
Superior Indebtedness.  No payment on account of principal (and premium, if
any) or interest on the Subordinated Debentures may be made if, at the time
of such payment, or immediately after giving effect thereto, there exists a
default with respect to any Superior Indebtedness provided that no such
event of default will prevent payment on the Subordinated Debentures for
more than 180 days unless the holder of such Superior Indebtedness has
commenced judicial proceedings with respect to such default within such
period.  Upon payment or distribution of assets or securities of the
Company upon any liquidation, dissolution, winding-up or reorganization of
or similar proceedings relating to the Company, the holders of Superior
Indebtedness will be entitled to receive payment in full before the holders
of Subordinated Debentures are entitled to receive any payment.

By reason of such subordination, in the event of insolvency, creditors of
the Company who are holders of Superior Indebtedness may recover more,
ratably, than the holders of the Subordinated Debentures.

Prepayment of Debentures

The Company may, at any time after March 31, 1997, prepay the Notes in

                                                                  Page 56
whole or in part (in amounts of not less than $50,000) by payment of one
hundred ten percent (110%) of the principal amount of the Notes, or portion
thereof to be prepaid, and payment of the accrued interest thereon to the
date of prepayment.  The Company shall give written notice of any such
prepayment of the Debentures to each holder thereof not less than thirty
(30) days nor more than sixty (60) days before the date fixed for such
optional prepayment.  Such notice shall specify (i) such date, and (ii) the
principal amount of the holder's Debentures to be prepaid and the aggregate
principal amount of all Debentures to be prepaid. 

Upon the occurrence of either of the following events, and upon the written
request of any holder of the Debentures, the Company shall prepay such
holder's Debentures in whole by payment of one hundred percent (100%) of
the principal amount of the Debentures and payment of the accrued interest
thereon to the date of prepayment, within thirty (30) days of the Company's
receipt of such written request: (a) in the event that a person, who as of
May 15, 1996 owned no more than five percent (5%) of the issued and
outstanding shares of Common Stock of the Company (no preferred stocks
being issued and outstanding at such date), shall acquire ownership of that
portion of the issued and outstanding Common Stock and/or preferred stock
of the Company which in the aggregate possesses thirty-five percent (35%)
or more of the voting rights of all issued and outstanding shares of Common
Stock and preferred stock of the Company, or (b) in the event of the
consolidation with or merger of the Company with or into another
corporation or entity, or in the event of the sale, lease or conveyance to
another corporation or entity of the assets of the Company as an entirety
or substantially as an entirety.

Defaults and Remedies

An Event of Default under the Debenture Agreement is defined as: default
for 15 days in payment of interest on the Subordinated Debentures; default
in payment of principal of the Subordinated Debentures at maturity; failure
by the Company for 30 days after notice to it to comply with any of its
other covenants in the Debenture Agreement; the sale by the Company of all
or substantially all of its assets; and certain events of bankruptcy,
insolvency or reorganization.  If an Event of Default occurs and is

                                                                  Page 57
continuing, the holder of a Subordinated Debenture may, upon 10 days prior
written notice, declare his Subordinated Debenture to be due and payable
immediately, provided that the holders of 51% of the aggregate principal
amount of the Debentures may waive any such Event of Default.

Modification and Amendment

Modification and amendment of the Debenture Agreement may be effected by
the Company with the consent of the holders of 66 2/3% of the aggregate
principal amount of the Subordinated Debentures, provided that no such
modification or amendment may, without the consent of each holder affected
thereby: reduce the amount of Subordinated Debentures whose holders must
consent to an amendment; reduce the rate or change the time and place for
payment of interest on any Subordinated Debenture; reduce the principal of
or change the fixed maturity of any Subordinated Debenture; or make any
Debenture convertible into any securities other than as described in the
Debenture Agreement.

Common Stock
   
The Company's Articles of Incorporation authorize 25,000,000 shares of
Common Stock with a par value of $.10 per share.  Each holder of Common
Stock is entitled to one vote per share held of record at each meeting of
the stockholders.  As of April 21, 1997, there were 6,315,738 shares of the
Company's Common Stock outstanding.  Subject to the rights of the holders
of shares of Preferred Stock which are issued and outstanding from time to
time, holders of Common Stock are entitled to such dividends as may be
declared from time to time by the Board of Directors of the Company out of
funds legally available therefor and to participate pro-rata in dividends
and, upon liquidation, any distribution to stockholders.  The Common Stock
carries no preemptive, subscription, or cumulative voting rights or
redemption or sinking fund provisions.
    

The Articles of Incorporation and Bylaws of the Company provide
authorization for dividing the Board of Directors into three separate
classes having staggered terms so that only one-third of the total number
of directors is up for election at each annual meeting of the shareholders

                                                                  Page 58
of the Company.  The Articles of Incorporation also provide that the
provision authorizing such a classification of the Board of Directors may
not be amended, altered, changed or repealed in any respect without an
affirmative vote of the holders of not less than eighty percent (80%) of
the then outstanding shares of capital stock of the Company at a meeting
called for such purpose.  At the present time, the Company does not
anticipate that a division of the Board of Directors into three separate
classes with each class having a staggered term, as provided above, will be
placed into effect.

Executive Compensation."

                            PLAN OF DISTRIBUTION

   
Certain Selling Security Holders are offering for sale pursuant to this
Prospectus a total of 1,150,350 shares of Preferred Stock and a total of
737,174 Warrants of the Company.  Additionally, certain Selling Security
Holders are offering for sale pursuant to this Prospectus a total of
900,506 shares of Common Stock of the Company.  In addition, 887,174 shares 
of Common Stock are issuable by the Company upon the exercise of 887,174 
Warrants and up to 7,669,000 shares of Common Stock are issuable by the Company 
upon the conversion of 1,150,350 shares of Preferred Stock.  Such Common 
Stock will be offered for sale by the holders thereof in the event such 
Warrants are exercised or such Preferred Stock is converted by the holders 
or any subsequent holder of such Warrants or Preferred Stock.  No commissions 
will be paid in connection with such exercise or conversion.  The Warrants and 
shares of Preferred Stock and Common Stock offered for sale by the Selling 
Security Holders will be offered for sale to the public (if at all) only in 
such amounts as determined in each such holder's sole discretion.
    

It is anticipated that the Warrants and the shares of Preferred Stock and
Common Stock will be offered in the NASDAQ SmallCap Market (or, if not
available for the Warrants or the Preferred Stock, the over-the-counter
market)  or in negotiated transactions or block trades, at fixed prices
which may be changed, at market prices prevailing at the time of sale, at
prices related to such prevailing market prices, or at negotiated prices.
The Warrants and the shares of Preferred Stock and Common Stock offered
hereby may be sold from time to time on a best efforts basis through
registered broker-dealers, to be selected by the Selling Security Holders,
who may receive compensation in the form of discounts, concessions, or
commissions from the Selling Security Holders and/or the purchaser of
shares for whom such broker-dealer may act as agent or to whom they sell as
principal, or both (which compensation to a particular broker-dealer may be
in excess of customary commissions).  It is anticipated that the offering
will continue until all of the securities offered hereby are sold or until
the Company determines, in its sole discretion, that such offering should
cease.  

There is no underwriter or coordinating broker acting in connection with
this offering.  In effecting sales, brokers or dealers engaged by the
Selling Security Holders may arrange for other brokers or dealers to
participate.  Brokers or dealers will receive commissions or discounts from
Selling Security Holders in amounts negotiated immediately prior to the
sale.  Such brokers or dealers and any other participating brokers or
dealers may be deemed to be "underwriters" within the meaning of the

                                                                  Page 69
Securities Act of 1933 (the "Securities Act") in connection with such
sales.  In addition, each Selling Security Holder may be deemed to be an
"underwriter" within the meaning of the Securities Act with respect to the
securities offered by him.  Any securities covered by this Prospectus which
qualify for sale pursuant to Rule 144 promulgated under the Securities Act
may be sold under Rule 144 rather than pursuant to this Prospectus.

In order to comply with certain states' securities laws, if applicable, the
Warrants and shares of Preferred Stock and Common Stock will be sold in
such jurisdictions only through registered or licensed brokers or dealers. 
In addition, in certain states the Warrants and shares of Preferred Stock
and Common Stock may not be sold unless the Warrants, Preferred Stock, and
Common Stock have been registered or qualified for sale in such state or an
exemption from registration or qualification is available and is complied
with.


           LIABILITY AND INDEMNIFICATION OF OFFICERS AND DIRECTORS

As permitted by the provisions of the Texas Business Corporation Act, the
Articles of Incorporation of the Company eliminates in certain
circumstances the monetary liability of directors of the Company for a
breach of their fiduciary duty as directors.  These provisions do not
eliminate the liability of a director (i) for a breach of the director's
duty of loyalty to the corporation; (ii) for acts or omissions by a
director not in good faith or which involve intentional misconduct or a
knowing violation of law; (iii) for any transaction from which the director
derives an improper benefit whether or not the benefit resulted from an
action taken within the scope of the director's office; (iv) for an act or
omission for which the liability of a director is expressly provided by
statute; or (v) for an act related to an unlawful corporate distribution. 
In addition, these provisions do not limit the rights of the Company or its
stockholders, in appropriate circumstances, to seek equitable remedies such
as injunctive or other forms of non-monetary relief.  Such remedies may not
be effective in all cases.

                                                                  Page 70
The Company's Articles of Incorporation and Bylaws provide that the Company
shall indemnify all directors and officers of the Company to the full
extent permitted by the Texas Business Corporation Act.  Under such
provisions any director or officer who, in his capacity as such, is made or
threatened to be made a party to any suit or proceeding, shall be
indemnified if such director or officer acted in good faith and in a manner
he reasonably believed to be in, or not opposed to, the best interests of
the corporation.  The Articles of Incorporation, Bylaws, and the Texas
Business Corporation Act further provide that such indemnification is not
exclusive of any other rights to which such individuals may be entitled
under the Articles of Incorporation and the Bylaws or any other agreement,
vote of stockholders or disinterested directors, or otherwise.


                              LEGAL PROCEEDINGS

The Company is a defendant in various legal actions that arose out of the
normal course of business.  It is management's opinion, based on evaluation
and discussion with counsel, that the ultimate outcome of those matters
will not have a material adverse effect on the Company's financial position
or its results of operations.

responsibility is to express an opinion on these financial statements based
on our audits.

We conducted our audits in accordance with generally accepted auditing 
standards.  Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement.  An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial 
statement presentation.  We believe that our audits provide a reasonable 
basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in 
all material respects, the financial position of TGC Industries, Inc. as of 
December 31, 1996 and 1995, and the results of its operations and its cash 
flows for the years then ended, in conformity with generally accepted 
accounting principles.

NOTE A - NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING 
         POLICIES

   A summary of the significant accounting policies consistently applied in
   the preparation of the accompanying financial statements follows:
   
   Nature of Operations
   
   TGC Industries, Inc. (TGC or the Company) is engaged in the domestic
   geophysical services business and primarily conducts seismic surveys and
   sells gravity data to companies engaged in exploration in the oil
   and gas industry.  The operations of its former wholly-owned subsidiary,
   Chase Packaging Corporation (Chase), which manufactures woven paper mesh
   and polypropylene mesh fabric bags for agricultural and industrial use,
   are reflected as discontinued in the accompanying financial statements. 
   (See Note B).
   
   Cash Equivalents
   
   The Company considers all highly liquid investments with original
   maturity dates of three months or less to be cash equivalents.
   
   Property and Equipment
   
   Property and equipment are stated at cost.  Depreciation is provided
   using the straight-line method over the estimated useful lives of the
   individual assets.
   
   Income Taxes
   
   Deferred income taxes reflect the impact of temporary differences
   between the amounts of assets and liabilities recognized for financial
   reporting purposes and such amounts recognized for tax purposes.
   
   Stock-Based Compensation
   
   Statement of Financial Accounting Standards No. 123 (SFAS 123),
   "Accounting for Stock-Based Compensation" encourages, but does not
   require, companies to record compensation cost for stock-based
   employee compensation plans at fair value.  The Company has chosen to
   continue to account for stock-based compensation using the intrinsic
   value method prescribed in Accounting Principles Board Opinion No. 25
   (APB 25), "Accounting for Stock Issued to Employees" and provides the
   required pro forma disclosures prescribed by SFAS 123.

                         December 31, 1996 and 1995


NOTE A - NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING 
           POLICIES - Continued
   
   Revenue Recognition
   
   Revenues from conducting seismic surveys are recognized over the term of
   the contract using the percentage-of-completion method.  Under this
   method, revenues are recognized on the units-of-production method. 
   Revenues for the sale of gravity data are recognized when services are
   rendered. 
   
   Earnings (Loss) Per Share
   
   Earnings (loss) per common share is based upon the weighted average
   number of shares of common stock outstanding.  When dilutive, stock
   options are included as common stock equivalents using the treasury
   stock method. Fully diluted earnings (loss) per share have not been
   presented because they result in an improvement of earnings (loss) per
   common share.
   
   Use of Estimates
   
   The preparation of financial statements in conformity with generally
   accepted accounting principles requires management to make estimates and
   assumptions that affect the reported amounts of assets and liabilities
   and disclosure of contingent assets and liabilities at the date of the
   financial statements and the reported amounts of revenues and expenses
   during the reporting period.  Actual results could differ from those
   estimates.

NOTE B - REORGANIZATION PLAN

   In May 1996, a formal plan was adopted to reorganize TGC and Chase.
   Pursuant to the plan, the following actions have been taken:
   
   (a) During July 1996, the Company issued 1,150,350 shares of Series C 8%
       convertible exchangeable preferred stock in a private placement
       offering with gross proceeds of approximately $5,800,000.  The
       preferred stock is, at the option of the Company, exchangeable into
       8% subordinated convertible debentures.  The preferred stock and
       debentures are convertible into shares of the Company's common stock
       for a period of four years and are convertible in years one and two
       at $.75 per share, year three at $1.25 and thereafter at $2.00.
   
   (b) Upon closing of the private placement, the Company contributed
       $2,716,403 as a capital contribution to Chase.

                                   F-16

                         December 31, 1996 and 1995




NOTE B - REORGANIZATION PLAN - Continued
   
   (c) TGC liquidated its wholly-owned subsidiary, Chase Packaging
       Corporation (Old Chase), with TGC receiving all of Old Chase's
       properties and liabilities in cancellation of the Old Chase stock
       held by TGC.  TGC formed a new wholly-owned subsidiary, New Chase
       Corporation (New Chase), and subsequently changed the name to Chase
       Packaging Corporation.  TGC transferred all of the properties and
       liabilities received in the liquidation of Old Chase to New Chase,
       except TGC retained the manufacturing facility of Old Chase located
       in Portland, Oregon.  On March 18, 1997, TGC sold the facility for
       proceeds of approximately $2,400,000.  TGC applied such proceeds in  
       satisfaction of the mortgage indebtedness with respect to such       
       facility and in satisfaction of a debt obligation owing by TGC to    
       New Chase to pay to New Chase any such proceeds in excess of the     
       amount of the mortgage indebtedness.
   
   (d) During June 1996, the Board of Directors approved the spin-off of
       New Chase whereby all of the shares of New Chase would be
       distributed as a stock dividend to the shareholders of TGC common
       stock and, on an as if converted basis, TGC preferred stock,
       effective July 31, 1996.  The New Chase common stock was distributed
       on March 7, 1997.

   Accordingly, the operations of Chase have been classified as
   discontinued in the accompanying financial statements.  Summary
   operating results of the discontinued operations were as follows:

NOTE F - STOCKHOLDERS' EQUITY - Continued

   The Company currently has in effect a 1993 Stock Option Plan (the "1993
   Plan") covering a total of 750,000 shares of the Company's common stock,
   and options must be granted at prices at not less than the market price
   at the date of grant.  Options granted under the 1993 Plan must be
   exercised within five years from the date of grant.  Options covering
   350,000 shares are exercisable as follows:  (i) one-third of the shares
   after the first twelve-month period following the date of grant, (ii) up
   to two-thirds of the shares after the first twenty-four month period
   following the date of grant, and (iii) all of the shares of stock
   subject to the option at any time after the first thirty-six month
   period following the date of grant.  Options covering 185,500 shares are
   exercisable as follows:  (i) 44,500 shares at date of grant, (ii)
   125,000 shares after nine months following the date of grant, and (iii)
   the remaining 16,000 shares based on individual performance.  At
   December 31, 1996, outstanding options for 67,833 shares were 
   exercisable, and no options were available for future grant.
   
   The Company has adopted only the disclosure provisions of SFAS 123.  The
   Company will continue to apply APB 25 and related interpretations in
   accounting for its stock-based compensation plans.  Had compensation
   cost for the Company's 1996 stock grants for stock-based compensation
   plans been determined consistent with SFAS 123, the Company's net loss
   and net loss per common share for 1996 would approximate the pro forma

   The effects of applying SFAS 123 in this pro forma disclosure are not
   indicative of future disclosures because they do not take into effect
   pro forma compensation expense related to grants made before 1995.  The
   fair value of these options was estimated at the date of grant using the
   Black-Scholes option-pricing model with the following weighted average
   assumptions used for grants after 1994:  expected volatility of 150%;
   risk-free interest rate of 6.25%; and expected life of 4 years.  The
   weighted average fair value of options granted during 1996 was $.58.

NOTE H - 401(k) PLAN

   The Company has a 401(k) salary deferral plan which covers all employees
   who have reached the age of 20.5 years and have been employed by the
   Company for at least one year.  The covered employees may elect to have
   an amount deducted from their wages for investment in a retirement plan.
   The Company matches contributions to the plan at the following rates: 
   (1) 75% of each participant's salary reduction contributions to the plan
   up to a maximum of 3% of the participant's compensation; and (2)  50% of
   each participant's salary reduction contributions to the plan which are
   in excess of 3% of the participant's compensation but not in excess of
   8% of the participant's compensation.  The Company's matching
   contribution to the plan was approximately $30,000 and $29,000 for the

NOTE I - CONCENTRATION OF CREDIT RISK

   The Company sells its geophysical services to large oil and gas

   approximately 77% of accounts receivable at December 31, 1996.  At
   December 31, 1995, six customers accounted for approximately 96% of
   accounts receivable.

   sales of the Company, respectively.  During 1995, two  customers
   accounted for 21% and 12% of the sales of the Company, respectively.

NOTE J - FINANCIAL INSTRUMENTS

   The following methods and assumptions were used to estimate the fair
   value of financial instruments:

   Cash

   The carrying amount of cash approximates fair value due to the short
   term nature of the account.

   Long-term Obligations

   Fair value of long-term debt and capital lease obligations was estimated
   using current rates offered to the  Company for debt with similar
   maturities.

     RESOLVED, that pursuant to the authority vested in the Board of
Directors of the Corporation by Article 4.b of the Corporation's
Certificate of Restated Articles of Incorporation, as amended, a series of
preferred stock of the Corporation be, and it is hereby, created out of the
authorized but unissued shares of the capital stock of the Corporation,
such series to be designated Series C 8% Convertible Exchangeable Preferred
Stock (the "Preferred Stock"), to consist of 1,250,000 shares, to be
offered in a private placement at $5.00 per share, of which the preferences
and relative and other rights, and the qualifications, limitations or
restrictions thereof, shall be (in addition to those set forth in the
Corporation's Certificate of Incorporation, as amended) as follows:

     1.   Certain Definitions.  Unless the context otherwise requires, the

resolution, the meanings herein specified.

     Common Stock.  The term "Common Stock" shall mean all shares now or
hereafter authorized of any class of Common Stock of the Corporation and
any other stock of the Corporation, howsoever designated, authorized after
the Issue Date, which has the right (subject always to prior rights of any

                                                                      A-1
class or series of preferred stock) to participate in the distribution of
the assets and earnings of the Corporation without limit as to per share
amount.

     Conversion Date.  The term "Conversion Date" shall have the meaning
set forth in subparagraph 3(e) below.

     Conversion Ratio.  The term "Conversion Ratio" shall mean the ratio
used to determine the number of shares of Common Stock deliverable upon
conversion of the Preferred Stock, subject to adjustment in accordance with
the provisions of paragraph 3 below.

     Issue Date.  The term "Issue Date" shall mean the date that shares of
Preferred Stock are first issued by the Corporation.

     Market Price.  The term "Market Price" shall have the meaning set
forth in subparagraph 3(h) below.

     Private Placement Memorandum.  The term "Private Placement Memorandum"
shall mean the Confidential Private Placement Memorandum dated May 15,
1996, as amended, and related documents, pursuant to which the Corporation
is offering the Preferred Stock.

     Subsidiary.  The term "Subsidiary" shall mean any corporation of which
shares of stock possessing at least a majority of the general voting power
in electing the board of directors are, at the times as of which any
determination is being made, owned by the Corporation, whether directly or
indirectly through one or more Subsidiaries.

     2.   Dividends.  The Preferred Stock shall have the following dividend
rights:

          (a)  Declaration of Dividends.  The holders of shares of
Preferred Stock shall be entitled to receive cumulative cash dividends,
when and as declared by the Board of Directors out of funds legally
available therefor, at a rate of eight percent (8%) per annum and no more
($0.40 per share per annum based on a price per share of $5.00), before any

                                                                      A-2
dividend or distribution in cash or other property (other than dividends
payable in stock ranking junior to the Preferred Stock as to dividends and
upon liquidation, dissolution or winding-up) on any class or series of
stock of the Corporation ranking junior to the Preferred Stock as to
dividends or on liquidation, dissolution or winding-up shall be declared or
paid or set apart for payment.

          (b)  Payment of Dividends.  Dividends on the Preferred Stock
shall be payable, when and as declared by the Board of Directors on January
1 and July 1 of each year, commencing January 1, 1997 (each such date being
hereinafter individually a "Dividend Payment Date" and collectively the
"Dividend Payment Dates"), except that if such date is a Saturday, Sunday
or legal holiday then such dividend shall be payable on the first
immediately preceding calendar day which is not a Saturday, Sunday or legal
holiday, to holders of record as they appear on the books of the
Corporation on such respective dates, not exceeding sixty days preceding
such Dividend Payment Date, as may be determined by the Board of Directors
in advance of the payment of each particular dividend.  Dividends in
arrears may be declared and paid at any time, without reference to any
regular Dividend Payment Date, to holders of record on such date as may be
fixed by the Board of Directors of the Corporation.  Dividends declared and
paid in arrears shall be applied first to the earliest dividend period or
periods for which any dividends remain outstanding.  The amount of
dividends payable per share of this Series for each dividend period shall
be computed by dividing the annual rate of eight percent (8%) by two (2). 
Dividends payable on this Series for the initial period and for any period
less than a full quarterly period shall be computed on the basis of a
360-day year of twelve 30-day months.

          (c)  Dividends Cumulative.  Preferred Stock shall be cumulative
and accrue from and after the date of original issuance thereof, whether or
not declared by the Board of Directors.  Accrued dividends shall not bear
interest.

          (d)  Dividend Restriction.  No cash dividend may be declared on
any other class or series of stock ranking on a parity with the Preferred
Stock as to dividends in respect of any dividend period unless there shall

                                                                      A-3
also be or have been declared on the Preferred Stock like dividends for all
quarterly periods coinciding with or ending before such semi-annual period,
ratably in proportion to the respective annual dividend rates fixed
therefor.

     3.   Conversion Rights.  The Preferred Stock shall be convertible into
Shares of Common Stock as follows:

          (a)  Conversion Right.  The holder of any shares of Preferred
Stock shall have the right, at such holder's option, at any time to convert
any of such shares of Preferred Stock into fully paid and nonassessable
shares of Common Stock at the Conversion Ratio provided for in subparagraph
3(d) below by surrendering shares of Preferred Stock for conversion in
accordance with subparagraph 3(e) below.

          (b)  Continuance of Conversion Right.  The Conversion Right set
forth above will continue so long as such Preferred Stock is outstanding
with respect to any stock not (i) redeemed in accordance with the terms of
paragraph 7, or (ii) exchanged pursuant to the terms of paragraph 9, prior
to the exercise of such conversion right.

          (c)  Surrender of Shares on Exercise of Conversion Right.  In the
event that any holder of shares of Preferred Stock surrenders such shares
for conversion, such holder will be issued the number of shares of Common
Stock to which such holder is entitled pursuant to the provisions of
subparagraph 3(d) in the manner provided for in subparagraph 3(e).  The
shares of Preferred Stock deemed to have been surrendered will have the
status described in paragraph 11 below.

          (d)  Conversion Ratio.  Each share of Preferred Stock may, at the
discretion of the holder thereof, be converted into shares of Common Stock
of the Corporation at the conversion price per share of (i) prior to the
close of business on July 1, 1998, the conversion price per share of Common
Stock of Seventy-Five Cents ($0.75), (ii) after July 1, 1998 and prior to
the close of business on July 1, 1999, the conversion price per share of
Common Stock of One Dollar and Twenty-Five Cents ($1.25), and (iii)
thereafter, the conversion price per share of Common Stock of Two Dollars

                                                                      A-4
($2.00), as such conversion price may be adjusted and readjusted from time
to time in accordance with subparagraph 3(g) hereof (such conversion price,
as adjusted and readjusted and in effect at any time, being herein called
the "Conversion Price" or the "Conversion Ratio"), into the number of fully
paid and non- assessable shares of Common Stock determined by dividing (x)
the $5.00 per share price of the Preferred Stock to be so converted by (y)
the Conversion Price in effect at the time of such conversion.  The
Conversion Ratios referred to above will be subject to adjustment as set
forth in subparagraph 3(g). 

          (e)  Mechanics of Conversion.  The holder of any shares of
Preferred Stock may exercise the conversion right specified in subparagraph
3(a) by surrendering to the Corporation or any transfer agent of the
Corporation the certificate or certificates for the shares to be converted,
accompanied by written notice specifying the number of shares to be
converted. Conversion shall be deemed to have been effected upon receipt of
the certificate or certificates for the shares to be converted accompanied
by written notice of election to convert specifying the number of shares to
be converted.  The date of such receipt is referred to herein as the
"Conversion Date."  As promptly as practicable thereafter (and after
surrender of the certificate or certificates representing shares of
Preferred Stock to the Corporation or any transfer agent of the
Corporation) the Corporation shall issue and deliver to or upon the written
order of such holder a certificate or certificates for the number of full
shares of Common Stock to which such holder is entitled and a check or cash
with respect to any fractional interest in a share of Common Stock as
provided in subparagraph 3(f).  The person in whose name the certificate or
certificates for Common Stock are to be issued shall be deemed to have
become a holder of record of such Common Stock on the applicable Conversion
Date. Upon conversion of only a portion of the number of shares covered by
a certificate representing shares of Preferred Stock surrendered for
conversion, the Corporation shall issue and deliver to or upon the written
order of the holder of the certificate so surrendered for conversion, at
the expense of the Corporation, a new certificate covering the number of
shares of Preferred Stock representing the unconverted portion of the
certificate so surrendered.

                                                                      A-5

          (f)  Fractional Shares.  No fractional Shares or scrip shall be
issued upon conversion of shares of Preferred Stock. If more than one share
of Preferred Stock shall be surrendered for conversion at any one time by
the same holder, the number of shares of Common Stock issuable upon
conversion thereof shall be computed on the basis of the aggregate number
of shares of Preferred Stock so surrendered. Instead of any fractional
shares which would otherwise be issuable upon conversion of any shares of
Preferred Stock, the Corporation shall pay a cash adjustment in respect of
such fractional interest in an amount equal to that fractional interest of
the then Current Market Price.

          (g)  Conversion Ratio Adjustments.  The Conversion Ratio shall be
subject to adjustment from time to time as follows:

               (i)  Stock Dividends, Subdivisions, Reclassifications or
Combinations.  If the Corporation shall (x) declare a dividend or make a
distribution on its Common Stock in shares of its Common Stock, (y)
subdivide or reclassify the outstanding shares of Common Stock into a
greater number of shares, or (z) combine or reclassify the outstanding
Common Stock into a smaller number of shares, the Conversion Ratio in
effect at the time of the record date for such dividend or distribution or
the effective date of such subdivision, combination or reclassification
shall be proportionately adjusted so that the holder of any shares of
Preferred Stock surrendered for conversion after such date shall be
entitled to receive the number of shares of Common Stock which he would
have owned or been entitled to receive had such Preferred Stock been
converted immediately prior to such date. Successive adjustments in the
Conversion Ratio shall be made whenever any event specified above shall
occur.

              (ii)  Other Distributions.  In case the Corporation shall fix
a record date for the making of a distribution to all holders of shares of
its Common Stock (w) of shares of any class other than its Common Stock or
(x) of evidence of indebtedness of the Corporation or any Subsidiary or (y)
of assets (excluding cash dividends or distributions, and dividends or
distributions referred to in subparagraph 3(g)(i) above), or (z) of rights
or warrants, in each such case the Conversion Ratio in effect immediately

                                                                      A-6
prior thereto shall be immediately thereafter proportionately adjusted for
such distribution so that the holder of Preferred Stock would be entitled
to receive the fair market value (as determined by the Board of Directors,
whose determination shall be conclusive) of what he would have been
entitled to receive had such Preferred Stock been converted prior to such
distribution.  Such adjustment shall be made successively whenever such a
record date is fixed. In the event that such distribution is not so made,
the Conversion Ratio then in effect shall be readjusted, effective as of
the date when the Board of Directors determines not to distribute such
shares, evidences of indebtedness, assets, rights or warrants, as the case
may be, to the Conversion Ratio which would then be in effect if such
record date had not been fixed.

             (iii)  Consolidation, Merger, Sale, Lease or Conveyance.  In
case of any consolidation with or merger of the Corporation with or into
another corporation or entity, or in case of any sale, lease or conveyance
to another corporation or entity of the assets of the Corporation as an
entirety or substantially as an entirety, each share of Preferred Stock
shall after the date of such consolidation, merger, sale, lease or
conveyance be convertible into the number of shares of stock or other
securities or property (including cash) to which the shares of Common Stock
issuable (at the time of such consolidation, merger, sale, lease or
conveyance) upon conversion of such share of Preferred Stock would have
been entitled upon such consolidation, merger, sale, lease or conveyance;
and in any such case, if necessary, the provisions set forth herein with
respect to the rights and interests thereafter of the holders of the shares
of Preferred Stock shall be appropriately adjusted so as to be applicable,
as nearly as may reasonably be, to any shares of stock or other securities
or property thereafter deliverable on the conversion of the shares of
Preferred Stock.

          (h)  Market Price.  The Market Price shall mean the daily closing
price per Share (as adjusted for any stock dividend, split, combination or
reclassification that took effect during the period under consideration).
The closing price for each day shall be the last reported sale price or, in
case no such reported sale takes place on such day, the average of the last
closing bid and asked prices, in either case on the principal national

                                                                      A-7
securities exchange on which the Common Stock is listed or admitted to
trading, or if not listed or admitted to trading on any national securities
exchange, the closing sale price for such day reported by NASDAQ, if the
Common Stock is traded over-the-counter and quoted in the National Market
System, or if the Common Stock is so traded, but not so quoted, the average
of the closing reported bid and asked prices of the Common Stock as
reported by NASDAQ or any comparable system or, if the Common Stock is not
listed on NASDAQ or any comparable system, the average of the closing bid
and asked prices as furnished by two members of the National Association of
Securities Dealers, Inc. selected from time to time by the Corporation for
that purpose. If the Common Stock is not traded in such manner that the
quotations referred to above are available, Market Price per Share shall be
deemed to be the fair value as determined by the Board of Directors,
irrespective of any accounting treatment.

          (i)  Statement Regarding Adjustments.  Whenever the Conversion
Ratio shall be adjusted as provided in subparagraph 3(g), the Corporation
shall forthwith file, at the office of any transfer agent for the Preferred
Stock and at the principal office of the Corporation, a statement showing
in detail the facts requiring such adjustment and the Conversion Ratio that
shall be in effect after such adjustment, and the Corporation shall also
cause a copy of such statement to be sent by mail, first class postage
prepaid, to each holder of shares of Preferred Stock at its address
appearing on the Corporation's records. Where appropriate, such copy may be
given in advance and may be included as part of a notice required to be
mailed under the provisions of subparagraph 3(j).

          (j)  Notice to Holders.  In the event the Corporation shall
propose to take any action of the type described in clause (i), (ii) or
(iii) of subparagraph 3(g), the Corporation shall give notice to each
holder of shares of Preferred Stock, in the manner set forth in
subparagraph 3(i), which notice shall specify the record date, if any, with
respect to any such action and the approximate date on which such action is
to take place. Such notice shall also set forth such facts with respect
thereto as shall be reasonably necessary to indicate the effect of such
action (to the extent such effect may be known at the date of such notice)
on the Conversion Ratio and the number, kind or class of shares which shall

                                                                      A-8
be deliverable upon conversion of shares of Preferred Stock. In the case of
any action which would require the fixing of a record date, such notice
shall be given at least 10 days prior to the date so fixed, and in case of
all other action, such notice shall be given at least 15 days prior to the
taking of such proposed action. Failure to give such notice, or any defect
therein, shall not affect the legality or validity of any such action.

          (k)  Treasury Stock.  For the purposes of this paragraph 3, the
sale or other disposition of any Common Stock theretofore held in the
Corporation's treasury shall be deemed to be an issuance thereof.

          (l)  Costs.  The Corporation shall pay all documentary, stamp,
transfer or other transactional taxes attributable to the issuance or
delivery of shares of Common Stock upon conversion of any shares of
Preferred Stock; provided that the Corporation shall not be required to pay
any taxes which may be payable in respect of any transfer involved in the
issuance or delivery of any certificate for such shares in a name other
than that of the holder of the shares of Preferred Stock in respect of
which such shares are being issued.

          (m)  Reservation of Shares.  The Corporation shall reserve at all
times so long as any shares of Preferred Stock remain outstanding, free
from preemptive rights, out of its treasury stock (if applicable) or its
authorized but unissued shares of Common Stock, or both, solely for the
purpose of effecting the conversion of the shares of Preferred Stock,
sufficient shares of Common Stock to provide for the conversion of all
outstanding shares of Preferred Stock.

          (n)  Approvals.  If any shares of Common Stock to be reserved for
the purpose of conversion of shares of Preferred Stock require registration
with or approval of any governmental authority under any Federal or state
law before such shares may be validly issued or delivered, then the
Corporation will in good faith and as expeditiously as possible endeavor to
secure such registration or approval, as the case may be. If, and so long
as, any shares of Common Stock into which the shares of Preferred Stock are
then convertible are listed on any national securities exchange, the
Corporation will, if permitted by the rules of such exchange, list and keep

                                                                      A-9
listed on such exchange, upon official notice of issuance, all such shares
issuable upon conversion.

          (o)  Valid Issuance.  All shares of Common Stock which may be
issued upon conversion of the shares of Preferred Stock will upon issuance
by the Corporation be duly and validly issued, fully paid and nonassessable
and free from all taxes, liens and charges with respect to the issuance
thereof, and the Corporation shall take no action which will cause a
contrary result.

     4.   Voting Rights.  The holders of the shares of the Preferred Stock
will be entitled to one vote per share of Preferred Stock held by them to
vote upon all matters which the holders of shares of the Company's Common
Stock shall have the right to vote.  In all cases, as a matter of law,
where the holders of shares of Preferred Stock shall have the right to vote
separately as a class, such holders will also be entitled to one vote per
share of Preferred Stock held by them.

     The affirmative vote or consent of the holders of at least two-thirds
of the outstanding shares of the Preferred Stock, voting as a class, will
be required to (i) authorize, create or issue, or increase the authorized
or issued amount of, shares of any class or series of stock ranking prior
to the Preferred Stock, either as to dividends or upon liquidation, or (ii)
amend, alter or repeal (whether by merger, consolidation or otherwise) any
provisions of the Company's Articles of Incorporation or of the Statement
of Resolution establishing this series of Preferred Stock so as to
materially and adversely affect the preferences, special rights or powers
of the Preferred Stock; provided, however, that any increase in the
authorized preferred stock or the creation and issuance of any other series
of preferred stock ranking on a parity with or junior to the Preferred
Stock shall not be deemed to materially and adversely affect such
preferences, special rights or powers.

     5.   Liquidation Rights.  Upon the dissolution, liquidation or winding
up of the Corporation, whether voluntary or involuntary, the holders of the
shares of this series of Preferred Stock shall be entitled to receive,
before any payment or distribution of the assets of the Corporation or

                                                                      A-10
proceeds thereof (whether capital or surplus) shall be made to or set apart
for the holders of the Common Stock or any other class or series of stock
ranking junior to the shares of this series of Preferred Stock upon
liquidation, the amount of $5.00 per share, plus a sum equal to all
dividends on such shares (whether or not earned or declared) accrued and
unpaid thereon to the date of final distribution, but such holders shall
not be entitled to any further payment.  If, upon any liquidation,
dissolution or winding-up of the Corporation, the assets of the
Corporation, or proceeds thereof, distributable among the holders of shares
of the Preferred Stock and any other class or series of preferred stock
ranking on a parity with the Preferred Stock as to payments upon
liquidation, dissolution or winding-up shall be insufficient to pay in full
the preferential amount aforesaid, then such assets or the proceeds thereof
shall be distributed among such holders ratably in accordance with the
respective amounts which would be payable on such shares if all amounts
payable thereon were paid in full.  For the purposes of this paragraph 5,
the voluntary sale, conveyance, lease, exchange or transfer (for cash,
shares of stock, securities or other consideration) of all or substantially
all the property or assets of the Corporation to, or a consolidation or
merger of the Corporation with, one or more corporations (whether or not
the Corporation is the corporation surviving such consolidation or merger)
shall not be deemed to be a liquidation, dissolution or winding-up,
voluntary or involuntary.

     6.   Registration Rights.   

          (a)  Registration on Request.  Upon the written request of any
holder or holders of at least 25% in the aggregate number of shares of the
Preferred Stock and/or shares of Common Stock ("Shares") issued upon
conversion of such Preferred Stock (provided that in computing such 25%
amount the number of shares of Preferred Stock and Common Stock shall be
weighted proportionately taking into account the Conversion Ratio with
respect to which such shares of Common Stock were issued upon conversion),
which request shall state the intended method of disposition by such holder
or holders and shall request that the Company effect the registration of
all or part of such Shares, or the Shares issuable upon the conversion of
such Preferred Stock, or both, under the Securities Act of 1933, as amended

                                                                      A-11
(the "Act"), the Company will promptly give written notice of such
requested registration to all holders of outstanding Preferred Stock and
Shares, and thereupon will use its best efforts to effect the registration
under the Act of:

     (i)  the Shares which the Company has been so requested to register,
     for disposition in accordance with the intended method of disposition
     stated in such request, and

     (ii) all other outstanding Shares, or Shares issuable upon the
     conversion of Preferred Stock, the holders of which shall have made
     written request (stating the intended method of disposition of such
     securities by such holders) to the Company for registration thereof
     within thirty (30) days after the receipt of such written notice from
     the Company,

all to the extent requisite to permit the disposition (in accordance with
the intended methods thereof as aforesaid) by the holders of the Shares so
registered and to maintain such registration in effect for a period of
twenty-four (24) months from the closing of the private placement under the
Private Placement Memorandum; provided, that the Company shall not be
required to register or use its best efforts to effect any registration of
Shares under the Act pursuant to this paragraph 6(a) more than once. 

     The Company shall have no obligation to register or use its best
efforts to effect any registration of Shares under the Act pursuant to this
paragraph 6 which would be in conflict with the obligations of any holder
or holders of Preferred Stock and/or Shares under any confidentiality
agreement between such holder or holders and the Company entered into in
connection with the offering of the Preferred Stock to such holder or
holders.

          (b)  Incidental Registration.  If the Company at any time
proposes to register any of its securities under the Act (otherwise than
pursuant to paragraph 6(a) and other than a registration on Form S-8, or
the form, if any, which supplants such Form), it will at such time give
written notice to all holders of outstanding Preferred Stock and Shares of

                                                                      A-12
its intention to do so and, upon the written request of any such holder
made within thirty (30) days after the receipt of any such notice (which
request shall specify the Shares intended to be disposed of by such holder
and state the intended method of disposition thereof), the Company will use
its best efforts to cause all such outstanding Shares, or Shares issuable
upon the conversion of Preferred Stock, the holders of which shall have so
requested the registration thereof, to be registered under the Act to the
extent requisite to permit the disposition (in accordance with the intended
methods thereof as aforesaid) of the Shares so registered; provided that,
if in the good faith judgment of the managing underwriter or underwriters
of a then proposed public offering of the Company's securities, such
registration of such Shares would materially and adversely affect such
public offering, then in such event the number of Shares and other
securities to be registered by the Company shall each be proportionally
reduced to such number as shall be acceptable to the managing underwriter.

          (c)  Registration Procedures.  If and whenever the Company is
required to use its best efforts to effect or cause the registration of any
Shares under the Act as provided in this paragraph 6, the Company will, as
expeditiously as possible:

     (i)  prepare and file with the Securities and Exchange Commission (the
     "Commission") a registration statement with respect to such Shares and
     use its best efforts to cause such registration statement to become
     effective;

     (ii) prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     statement effective for such period not exceeding twenty-four (24)
     months from the closing of the private placement under the Private
     Placement Memorandum as may be necessary to comply with the provisions
     of the Act with respect to the disposition of all Shares covered by
     such registration statement during such period in accordance with the
     intended methods of disposition by the seller or sellers thereof set
     forth in such registration statement;


                                                                      A-13

     (iii) furnish to each seller of such Shares such number of copies of
     such registration statement and of each such amendment and supplement
     thereto (in each case including all exhibits), such number of copies
     of the prospectus included in such registration statement (including
     each preliminary prospectus and, if any seller shall so request, a
     summary prospectus), in conformity with the requirements of the Act,
     and such other documents, as such seller may reasonably request in
     order to facilitate the disposition of the Shares owned by such
     seller;

     (iv) use its best efforts to register or qualify such Shares covered
     by such registration statement under such other securities or blue sky
     laws of such jurisdictions as each seller shall reasonably request and
     as agreed to by the Corporation, and do any and all other acts and
     things which may be reasonably necessary or advisable to enable such
     seller to consummate the disposition in such jurisdictions of the
     Shares owned by such seller; and

     (v)  notify each seller of any such Shares covered by such

     the Act, against any losses, claims, damages, or liabilities, joint or
     several, to which such seller or underwriter or controlling person may
     become subject, under the Act or otherwise, insofar as such losses,
     claims, damages, or liabilities (or actions in respect thereof) arise
     out of or are based upon (x) any untrue statement or alleged untrue
     statement of any material fact contained, on the effective date
     thereof, in any registration statement under which such securities
     were registered under the Act, any preliminary prospectus or final
     prospectus contained therein, or any amendment or supplement thereto,
     or (y) any omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading; and the Company will reimburse such seller and
     each such underwriter and each such controlling person for any legal
     or any other expenses reasonably incurred by them in connection with
     investigating or defending any such loss, claim, damage, liability, or
     action, provided that the Company shall not be liable in any such case
     to the extent that any such loss, claim, damage, or liability arises

     statement or omission or alleged omission made in such registration
     statement, any such preliminary prospectus, final prospectus,
     amendment or supplement in reliance upon and in conformity with
     written information furnished to the Company through an instrument

                                                                      A-15

     the preparation thereof.

     (ii) The Company may require, as a condition to including any Shares
     in any registration statement filed pursuant to paragraph 6(c), that
     the Company shall have received an undertaking satisfactory to it from
     the prospective seller of such Shares and from each underwriter of
     such  Shares, to indemnify and hold harmless (in the same manner and
     to the same extent as set forth in paragraph 6(e)(i)) the Company,
     each director of the Company, each officer of the Company who shall
     sign such registration statement and any person who controls the
     Company within the meaning of the Act, with respect to any statement
     or omission from such registration statement, any preliminary

     supplement thereto, if such statement or omission was made in reliance
     upon and in conformity with written information furnished to the
     Company through an instrument duly executed by such seller or
     underwriter specifically for use in the preparation of such
     registration statement, preliminary prospectus, final prospectus,
     amendment, or supplement.

     (iii) Promptly after receipt by an indemnified party of notice of
     the commencement of any action involving a claim referred to in the
     preceding subparagraphs of this paragraph 6(e), such indemnified party
     will, if a claim in respect thereof is to be made against an
     indemnifying party, give written notice to the latter of the
     commencement of such action, provided that the failure of any
     indemnified party to give notice as provided therein shall not relieve
     the indemnifying party of its obligations under the preceding
     subdivisions of this paragraph 6(e). In case any such action is
     brought against an indemnified party, the indemnifying party will be
     entitled to participate in and to assume the defense thereof, jointly
     with any other indemnifying party similarly notified to the extent
     that it may wish, with counsel reasonably satisfactory to such
     indemnified party, and after notice from the indemnifying party to
     such indemnified party of its election so to assume the defense
     thereof the indemnifying party will not be liable to such indemnified
     party for any legal or other expenses subsequently incurred by the

                                                                      A-16

     latter in connection with the defense thereof.  No indemnifying party,
     in the defense of any such claim or litigation, shall, except with the
     consent of each indemnified party, consent to entry of any judgment or
     enter into any settlement which does not include as an unconditional
     term thereof the giving by the claimant or plaintiff to such
     indemnified party of a release from all liability in respect to such
     claim or litigation.

     7.   Redemption Rights.  

          (a) Company's Redemption Option.  Except for any redemption which
the Company would be prohibited from effecting under applicable law, and
provided the shares of Preferred Stock of a holder have not earlier been
converted or exchanged in accordance with the provisions hereof, the shares
of Preferred Stock may be redeemed by the Company, in whole or in part, at
the option of the Company upon written notice by the Company to the holders
of Preferred Stock at any time after July 1, 2000, in the event that the
Preferred Stock of one or more holders has not been converted or exchanged
pursuant to the terms hereof on or before such date.  The Company shall
redeem each share of Preferred Stock of such holders within thirty (30)
days of the Company's delivery of the above notice to such holders and such
holders shall surrender the certificate(s) representing such shares of
Preferred Stock.  For any partial redemptions the Company shall redeem
shares in proportion to the number of shares held by each holder.  The
redemption amount shall be $5.00 per share, plus in each case accrued and
unpaid dividends thereon to the date of payment of such amount (the total
sum so payable on any such redemption being herein referred to as the
"redemption price"); provided, however, that for any such redemption which
is effected (i) on or after July 1, 2001 but prior to July 1, 2002, a
premium of ten percent (10%) of the per share amount of such Preferred
Stock shall be paid per share (i.e. $0.50 per share of Preferred Stock),
(ii) on or after July 1, 2002 but prior to July 1, 2003, a premium of 20%
per share (i.e. $1.00 per share); (iii) on or after July 1, 2003 but prior

(i.e. $2.00 per share); and on or after July 1, 2005 a premium of 50% per
share (i.e. $2.50 per share).

                                                                      A-17

          (b)  Redemption Notice.  Notice of any redemption pursuant to
this paragraph 7 shall be mailed to the party or parties required to
receive such notice at the principal office or residence address for such
party or parties.  Each such notice shall state: (1) the election of the
redemption option and the facts which give rise to such option; and (2) the
number of shares of Preferred Stock which are being elected to be redeemed. 
From and after the date of the Company's payment of the redemption price to
such holder or holders in accordance with such redemption notice (the
"redemption date"), notwithstanding that any certificates for such shares
shall not have been surrendered for cancellation, the shares represented
thereby shall no longer be deemed outstanding, the rights to receive
dividends and distributions shall cease to accrue from and after the
redemption date, and all rights of such holder or holders of the shares of
Preferred Stock as a stockholder of the Corporation with respect to such
shares, shall cease and terminate.
            
     8.   Exclusion of Other Rights.  Except as may otherwise be required
by law, the shares of Preferred Stock shall not have any preferences or
relative, participating, optional or other special rights, other than those
specifically set forth in this resolution (as such resolution may be
amended from time to time) and in the Corporation's Certificate of
Incorporation.  The shares of Preferred Stock shall have no preemptive or
subscription rights.

     9.   Exchange.  The shares of Preferred Stock shall be subject to the
following exchange provisions:

          (a)  Exchange for Debentures.  Shares of Preferred Stock are
exchangeable in whole by the Corporation, at its sole option, at any time
for the Corporation's 8% Subordinated Convertible Debentures, Series A due
the later of July 1, 2000 or two years from the date of exchange, as
described in the Corporation's Private Placement Memorandum; provided that
on or prior to the date of exchange the Corporation shall have paid to the
holders of outstanding shares of Preferred Stock all accumulated and unpaid
dividends to the date of exchange; and further provided that the
Corporation may not exercise such exchange option prior to January 1, 1998. 
Holders of outstanding shares of Preferred Stock will be entitled to

                                                                      A-18
receive $5.00 principal amount of Debentures in exchange for each share of
Preferred Stock held by them at the time of exchange; provided, however,
that for any such exchange which is effected on or after July 1, 2001, the
principal amount of Debentures exchanged for each share of Preferred Stock
shall include a premium as follows: (i) on or after July 1, 2001 but prior
to July 1, 2002, a premium of ten percent (10%) of the principal amount of
the Debenture per share (i.e. $0.50 per share of Preferred Stock, equal to
a Debenture in the amount of $5.50 per share), (ii) on or after July 1,
2002 but prior to July 1, 2003, a premium of 20% per share (i.e. $1.00 per
share, equal to a Debenture in the amount of $6.00 per share); (iii) on or
after July 1, 2003 but prior to July 1, 2004, a premium of 30% per share
(i.e. $1.50 per share, equal to a Debenture in the amount of $6.50 per
share); (iv) on or after July 1, 2004 but prior to July 1, 2005, a premium
of 40% per share (i.e. $2.00 per share, equal to a Debenture in the amount
of $7.00 per share); and on or after July 1, 2005 a premium of 50% per
share (i.e. $2.50 per share, equal to a Debenture in the amount of $7.50
per share).  The Corporation will mail to each holder of record of the
shares of Preferred Stock written notice of its intention to exchange no
less than thirty (30) nor more than sixty (60) days prior to the date fixed
for the exchange (the "exchange date").  Each such notice shall state:  (i)
the exchange date, (ii) the place or places where certificates for such
shares are to be surrendered for exchange into Debentures and (iii) that
dividends on the shares to be exchanged will cease to accrue on such
exchange date.  The terms of the Debentures are set forth in the Private
Placement Memorandum and "Exhibit B" thereto.  The Corporation will pay
interest on the Debentures at the rate and on the dates specified in such
Debentures from the exchange date.

          (b)  Status of Preferred Stock Following Exchange.  If notice has
been mailed as aforesaid, from and after the exchange date (unless default
shall be made by the Corporation in issuing Debentures in exchange for
shares of Preferred Stock or in making the final dividend payment on the
outstanding shares of Preferred Stock on the exchange date), dividends on
the shares of Preferred Stock shall cease to accrue, and such shares shall
no longer be deemed to be issued and outstanding, and all rights of the
holders thereof as stockholders of the Corporation (except the right to
receive from the Corporation the Debentures) shall cease and terminate. 

                                                                      A-19
Upon surrender in accordance with said notice of the certificates for any
shares so exchanged (properly endorsed or assigned for transfer, if the
Board of Directors shall so require and the notice shall so state), such
shares shall be exchanged by the Corporation into Debentures as aforesaid
and the holders thereof shall sign the Debenture Agreement with respect to
such Debentures in the form attached as Exhibit "B" to the Private
Placement Memorandum.

          (c)  Conversion Price for Debentures.  The conversion price per
share equivalent to the Conversion Ratio on any exchange date shall be the
initial conversion price for the Debentures.

     10.  Severability of Provisions.  If any right, preference or
limitation of the Preferred Stock set forth in this resolution (as such
resolution may be amended from time to time) is invalid, unlawful or
incapable of being enforced by reason of any rule or law or public policy,
all other rights, preferences and limitations set forth in this resolution
(as so amended) which can be given effect without the invalid, unlawful or
unenforceable right, preference or limitation herein set forth shall be
deemed enforceable and not dependent upon any other such right, preference
or limitation unless so expressed herein.

     11.  Status of Reacquired Shares.  Shares of Preferred Stock which
have been issued and reacquired in any manner shall (upon compliance with
any applicable provisions of the laws of the State of Texas) have the
status of authorized and unissued shares of Preferred Stock issuable in
series undesignated as to series and may be redesignated and reissued.

     Section 2.01.  Debenture.  If the Debenture is being received from the
Company upon issuance in exchange of the Company's Series C 8% Convertible
Exchangeable Preferred Stock, the Holder hereby agrees to receive such

Company hereby agrees to issue, convey, transfer, and assign to the Holder,

the Debenture records of the Company as follows: The Company shall maintain
a register of the issuance of the Debentures by recording the issuance

Company shall be entitled to recognize the person registered in the
register as the exclusive owner of a Debenture for the purposes of payment
of principal and interest thereon, and the Company shall not be bound to
recognize any equitable or other claim to or interest in such Debenture on

thereof, except as otherwise provided by applicable law.

     Section 2.05.  Interest on Debenture.  Interest shall be payable on
the outstanding principal amount of the Debenture at the rate set forth on
the face of the Debenture.  Interest on the Debenture shall be calculated

calculated semi-annually as of January 1 and July 1 of each year from the
Issuance Date through the last such date prior to the Maturity Date and on
the Maturity Date, and accrued interest as of each such date shall be due
and payable fifteen calendar days after each such date, provided that the
first such date on which interest shall be calculated and paid shall be the
first such semi-annual date following the exchange of the Company's Series
C 8% Convertible Exchangeable Preferred Stock for such Debenture.  If the
Company fails to pay to the Holder any portion of the interest that has
accrued on the principal amount of the Debenture when payment is due, such
unpaid portion of accrued interest shall continue to be due from and
payable by the Company to the Holder until paid.

     Section 2.06.  Lost or Stolen Certificates.  In the event the
certificate representing the Debenture is destroyed, misplaced, or stolen,
the Holder shall promptly notify the Company of such loss. In its

                                                                      B-6

discretion, the Company may, as a condition precedent to reissuing a new
Debenture certificate, require the Holder to do one or more of the
following things:

     (a)  Deliver a notice to the Company in the form prescribed by the
Company requesting the Company to stop transfer of such lost Debenture
certificate;

     (b)  Execute and deliver to the Company an affidavit of the facts
covering the loss of the Debenture certificate;

     (c)  Supply an indemnity bond in such sum as the Company may direct to
indemnify the Company against any claim that may be made against the
Company with regard to such lost Debenture certificate; and

     (d)  Execute and file any form required by any state or federal
regulatory authority in connection with the loss of the Debenture
certificate.

After the Holder has complied with such requirements as the Company deems
necessary and appropriate, the Company shall cancel the lost certificate in

                                SUBORDINATION

     Section 7.01.  Debentures Subordinated to Superior Indebtedness.
Anything in this Agreement or the Debentures to the contrary
notwithstanding, the indebtedness evidenced by the Debentures (such

the manner hereinafter set forth, to (but only to) all Superior
Indebtedness (as defined herein) of the Company. 

     Section 7.02.  Payments on Subordinated Indebtedness.

     Indebtedness, if either (i) notice of such default in writing or by
     telegram has been given to the Company by the holder or holders of
     such Superior Indebtedness; provided that judicial proceedings by the
     holders of such Superior Indebtedness shall be commenced with respect

     (including all principal, premium, if any, and interest, including
     interest accruing after the commencement of any such proceeding)
     before any payment or distribution of any character, whether in cash,
     securities, or other property (other than securities of the Company or
     any other corporation provided for by a plan of reorganization or
     readjustment or similar plan, the payment of which is subordinated, at
     least to the extend provided in this Article VII with respect to
     Subordinated Indebtedness, to the payment of all Superior Indebtedness

     least to the extent provided in this Article VII with respect to
     Subordinated Indebtedness, to the payment of all Superior Indebtedness
     at the time outstanding and to any securities issued in respect
     thereof under any such plan) which would otherwise (but for the terms
     hereof) be payable or deliverable in respect of any Subordinated
     Indebtedness, shall be paid or delivered directly to the holders of
     the Superior Indebtedness, until all Superior Indebtedness shall have
     been paid in full, the holders of the Subordinated Indebtedness at the
     time outstanding irrevocably authorize, empower, and direct all
     receivers, trustees, liquidators, conservators, fiscal agents, and
     others having authority in the premises to effect all such payments
     and deliveries;

               (iii) each holder of the Subordinated Indebtedness at the
     time outstanding irrevocably authorizes and empowers each holder of
     the Superior Indebtedness or such holder's representative to demand,
     sue for, collect, and receive such holder's ratable share of all such
     payments and distributions and to receipt therefor, and to file and
     prove all claims therefor and take all such other action, in the name  
     of such holder or otherwise, as such holder of the Superior
     Indebtedness or such holder's representative may determine to be
     necessary or appropriate for the enforcement of this Section 7.03; and

               (iv) the holders of the Subordinated Indebtedness shall
     execute and deliver to each holder of the Superior Indebtedness or
     such holder's representative all such further instruments confirming
     the above authorization, and all such powers of attorney, proofs of
     claim, assignments of claim, and other instruments, and shall take all
     such other action as may be requested by such holder of the Superior
     Indebtedness or such holder's representative to enforce all claims
      upon or in respect of the Subordinated Indebtedness.

For all purposes of this Agreement, Superior Indebtedness shall not be
deemed to have been paid in full unless the holders thereof shall have
received cash equal to the amount of principal, premium, if any, and
interest in respect of all Superior Indebtedness at the time outstanding,
and in case there are two or more holders of the Superior Indebtedness any

                                                                      B-14

payment or distribution required to be paid or delivered to the holders of
the Superior Indebtedness shall be paid or delivered to such holders
ratably according to the respective aggregate amounts remaining unpaid on
the Superior Indebtedness of such holders.

     Section 7.04.  Payments and Distributions Received.  If any payment or
distribution of any character (whether in cash, securities, or other
property) or any security shall be received by any holder of any of the
Subordinated Indebtedness in contravention of any of the terms of this
Article VII, and except as permitted by Section 7.03 or Section 7.06, such
payment or distribution or security shall be held in trust for the benefit
of, and shall be paid over or delivered and transferred to, the holders of
the Superior Indebtedness for application to the payment of all Superior
Indebtedness remaining unpaid, to the extent necessary to pay all such
Superior Indebtedness in full.  In the event of the failure of any holder
of any of the Subordinated Indebtedness to endorse or assign any such
payment, distribution or security, any holder of the Superior Indebtedness
or such holder's representative is hereby irrevocably authorized to endorse
or assign the same. 

     Section 7.05.  Subrogation.  In case cash, securities, or other
property otherwise payable and deliverable to the holders of the
Subordinated Indebtedness shall have been applied pursuant to Section 7.03
or Section 7.04 to the payment of Superior Indebtedness in full, then and
in each such case, the holders of the Subordinated Indebtedness shall be
subrogated to any rights of any holders of Superior Indebtedness to receive
further payments or distributions in respect of or applicable to the
Superior Indebtedness.

     Section 7.06.  Acceleration of Subordinated Indebtedness.  In case any
Subordinated Indebtedness is declared due and payable because of the
occurrence of a default or event of default under circumstances when the
terms of Section 7.03 are not applicable, the holders of such Subordinated
Indebtedness shall not be entitled to receive payment or distribution in
respect thereof until all Superior Indebtedness at the time outstanding
shall have been paid in full; provided, however, that the holders of the
Subordinated Indebtedness shall continue to be entitled to receive (i)

                                                                      B-15

current interest payments, (ii) regularly scheduled prepayments pursuant to
Section 3.01, and (iii) payments due at the stated maturity,
notwithstanding such declaration.

     Section 7.07.  Notice.  In the event that any Subordinated
Indebtedness shall become due and payable before its expressed maturity on
demand of the holder thereof as the result of the occurrence of a default
or event of default, the Company will give prompt notice in writing of such
happening to each holder of Superior Indebtedness.

     Section 7.08.  Subordination Not Affected, etc.  The terms of this
Article VII, the subordination effected hereby, and the rights of the
holders of the Superior Indebtedness shall not be affected by (a) any
amendment of or addition or supplement to any Superior Indebtedness or any
instrument or agreement relating thereto, (b) any exercise or non-exercise
of any right, power, or remedy under or in respect of any Superior
Indebtedness or any instrument or agreement relating thereto, or (c) any
waiver, consent, release, indulgence, extension, renewal, modification,
delay, or other action, inaction or omission, in respect of any Superior
Indebtedness or any instrument or agreement relating thereto or any
security therefor or guaranty thereof, whether or not any holder of any
Subordinated Indebtedness shall have had notice or knowledge of any of the
foregoing.

     Section 7.09.  Obligations Unimpaired.  No present or future holder of
Superior Indebtedness shall be prejudiced in the right to enforce
subordination of the Subordinated Indebtedness by any act or failure to act
on the part of the Company.  The provisions of this Article VII are solely
for the purpose of defining the relative rights of the holders of Superior
Indebtedness on the one hand and the holders of Subordinated Indebtedness
on the other hand, and nothing in this Article VII shall (a) impair as
between the Company and the holder of any Subordinated Indebtedness the
obligation of the Company, which is unconditional and absolute, to pay to
the holder thereof the principal, premium, if any, and interest thereon in
accordance with the terms thereof, or (b) prevent the holder of any
Subordinated Indebtedness from exercising all remedies otherwise permitted
by applicable law under this Agreement, subject to the rights, if any,

                                                                      B-16

under this Article VII of the holders of Superior Indebtedness.


                                ARTICLE VIII

                          CONVERSION OF DEBENTURES

     Section 8.01.  Conversion Privilege.  The unpaid principal amount of
any Debenture or any portion thereof may, at the election of the holder
thereof, at any time after the date of such Debenture be converted into
shares of Common Stock at the conversion price per share of (a) prior to
the close of business on July 1, 1998, the conversion price per share of
Common Stock of Seventy-Five Cents ($0.75), (b) after July 1, 1998 and
prior to the close of business on July 1, 1999, the conversion price per
share of Common Stock of One Dollar and Twenty-Five Cents ($1.25), and (c)
thereafter, the conversion price per share of Common Stock of Two Dollars
($2.00), as such conversion price may be adjusted and readjusted from time
to time in accordance with Section 8.05 hereof (such conversion price, as
so adjusted and readjusted and in effect at any time, being herein called
the Conversion Price), into the number of fully paid and non-assessable
shares of Common Stock determined by dividing (x) the aggregate principal
amount of the Debentures to be so converted by (y) the Conversion Price in
effect at the time of such conversion.

     Section 8.02.  Manner of Conversion; Partial Conversion, etc.  
          
     (a) Any Debenture may be converted in whole or in part by the holder
     thereof by surrender of such Debenture, accompanied by a written
     statement designating the principal amount of such Debenture to be
     converted and stating the name and address of the person in whose name
     certificates for shares of Common Stock are to be registered, at the
     office of the Company specified in or pursuant to Section 15.01.  Upon
     any such partial conversion of a Debenture, the Company at its expense
     will forthwith issue and deliver to or upon the order of the holder
     thereof a new Debenture or Debentures in principal amount equal to the
     unpaid and unconverted principal amount of such surrendered Debenture,
     such new Debenture or Debentures to be dated and to bear interest from

                                                                      B-17

     the date to which interest has been paid on such surrendered
     Debenture.  Each conversion shall be deemed to have been effected as
     of the close of business on the date on which such Debenture shall
     have been so surrendered to such office, and at such time the rights
     of the holder of such Debenture as such shall, to the extent of the
     principal amount thereof converted, cease, and the person or persons
     in whose name or names any certificate or certificates for shares of
     Common Stock shall be issuable upon such conversion shall be deemed to
     have become the holder or holders of record thereof.

     (b)  The Company shall pay all interest on any Debenture or portion of
     any Debenture surrendered for conversion to the date of such
     conversion.

     Section 8.03.  Delivery of Stock Certificates.  As promptly as
practicable after the conversion of any Debenture in full or in part, and
in any event within 20 days thereafter, the Company at its expense
(including the payment by it of any applicable issue taxes) will issue and
deliver to the holder of such Debenture, or as such holder (upon payment by
such holder of any applicable transfer taxes) may direct, a certificate or
certificates for the number of full and fractional shares of Common Stock
issuable upon such conversion.

     Section 8.04.  Shares to be Fully Paid; Reservation of Shares. The
Company covenants and agrees that all shares of Common Stock which may be
issued upon conversion of the Debentures will, upon issuance, be fully paid
and non-assessable and free from all taxes, liens, and charges with respect
to the issue thereof; and without limiting the generality of the foregoing,
the Company covenants and agrees that it will from time to time take all
such action as may be requisite to assure that the par value (if any) per
share of the Common Stock is at all times equal to or less than the then
effective purchase price per share of the Common Stock issuable upon
conversion of the Debentures.  The Company further covenants and agrees
that the Company will at all times have authorized, and reserved for the
purpose of issue or transfer upon the conversion of the Debentures, a
sufficient number of shares of its Common Stock to provide for the
conversion of the Debentures.

                                                                      B-18

     Section 8.05.   Conversion Ratio Adjustments.  The Conversion Ratio
shall be subject to adjustment from time to time as follows:

          (a)  Stock Dividends, Subdivisions, Reclassifications or
          Combinations.  If the Corporation shall (i) declare a dividend or
          make a distribution on its Common Stock in shares of its Common
          Stock, (ii) subdivide or reclassify the outstanding shares of
          Common Stock into a greater number of shares, or (iii) combine or
          reclassify the outstanding Common Stock into a smaller number of
          shares, the Conversion Price in effect at the time of the record
          date for such dividend or distribution or the effective date of
          such subdivision, combination or reclassification shall be
          proportionately adjusted so that the holder of any Debentures
          surrendered for conversion after such date shall be entitled to
          receive the number of shares of Common Stock which he would have
          owned or been entitled to receive had such Debentures been
          converted immediately prior to such date.  Successive adjustments
          in the Conversion Ratio shall be made whenever any event
          specified above shall occur.

          (b)  Other Distributions.  In case the Corporation shall fix a
          record date for the making of a distribution to all holders of
          shares of its Common Stock (i) of shares of any class other than
          its Common Stock or (ii) of evidences of indebtedness of the
          Corporation or any Subsidiary or (iii) of assets (excluding cash
          dividends or distributions, and dividends or distributions
          referred to in subparagraph 8.05(a) above), or (iv) of rights or
          warrants, in each such case the Conversion Price in effect
          immediately prior thereto shall be immediately thereafter
          proportionately adjusted for such distribution so that the holder
          of Debentures would be entitled to receive the fair market value
          (as determined by the Board of Directors, whose determination
          shall be conclusive) of what he would have been entitled to
          receive had such Debentures been converted prior to such
          distribution.  Such adjustment shall be made successively
          whenever such a record date is fixed.  In the event that such
          distribution is not so made, the Conversion Price then in effect

                                                                      B-19

          shall be readjusted, effective as of the date when the Board of
          Directors determines not to distribute such shares, evidences of
          indebtedness, assets, rights or warrants, as the case may be, to
          the Conversion Price which would then be in effect if such record
          date had not been fixed.

          (c)  Consolidation, Merger, Sale, Lease or Conveyance.  In case
          of any consolidation with or merger of the Corporation with or
          into another corporation, or in case of any sale, lease or
          conveyance to another corporation of the assets of the
          Corporation as an entirety or substantially as an entirety, the
          Debentures shall after the date of such consolidation, merger,
          sale, lease or conveyance be convertible into the number of
          shares of stock or other securities or property (including cash)
          to which the shares of Common Stock issuable (at the time of such
          consolidation, merger, sale, lease or conveyance) upon conversion
          of such Debenture would have been entitled to upon such
          consolidation, merger, sale, lease or conveyance; and in any such
          case, if necessary, the provisions set forth herein with respect
          to the rights and interests thereafter of the holders of the
          Debentures shall be appropriately adjusted so as to be
          applicable, as nearly as may reasonably be, to any shares of
          stock or other securities or property thereafter deliverable on
          conversion of the Debentures.

     Section 8.06.  Statement Regarding Adjustments.  Whenever the
Conversion Price shall be adjusted as provided in Section 8.05, the
Corporation shall forthwith file, at the principal office of the
Corporation, a statement showing in detail the facts requiring such
adjustment and the Conversion Price that shall be in effect after such
adjustment, and the Corporation shall also cause a copy of such statement
to be sent by mail, first class postage prepaid, to each holder of
Debentures, at its address appearing on the Corporation's records.  Where
appropriate, such copy may be given in advance and may be included as part
of a notice required to be mailed under the provisions of Section 8.07.

     Section 8.07.  Notice to Holders.  In the event the Corporation shall

                                                                      B-20

propose to take any action of the type described in Section 8.05, the
Corporation shall give notice to each holder of Debentures, in the manner
set forth in Section 8.06, which notice shall specify the record date, if
any, with respect to any such action and the approximate date on which such
action is to take place.  Such notice shall also set forth such facts with
respect thereto as shall be reasonably necessary to indicate the effect of
such action (to the extent such effect may be known at the date of such
notice) on the Conversion Price and the number, kind or class of shares
which shall be deliverable upon conversion of Debentures.  In the case of
any action which would require the fixing of a record date, such notice
shall be given at least 15 days prior to the taking of such action. 
Failure to give such notice, or any defect therein, shall not affect the
legality or validity of any such action.

     Section 8.08.  Costs.  The Corporation shall pay all documentary,
stamp, transfer or other transactional taxes attributable to the issuance
or delivery of shares of Common Stock upon conversion of any Debentures;
provided that the Corporation shall not be required to pay any taxes which
may be payable in respect of any transfer involved in the issuance or
delivery of any certificate for such shares in a name other than that of
the holder of the Debentures, in respect of which shares are being issued.

                            TRANSFER OF DEBENTURE

     Section 10.01.  Restriction on Transfer.  In addition to any other
restrictions on transfer of the Debenture imposed by this Article X, the
Holder may transfer or assign his, her, or its rights and obligations under
this Agreement only in conjunction with the transfer or assignment of the
Debenture.

     Section 10.02.  Requirements of Transfer.  No transfer of the
Debenture shall be valid and effective unless and until (a) the transferor

                                                                      B-23

executes a written assignment of the Debenture or executes a separate power
of attorney indicating his intent to transfer ownership, (b) the transferee
executes a Debenture Agreement, which shall be identical to this Agreement
except for the Holder's name and the date of execution, and (c) the
transferor delivers written transfer instructions (i) signed by the
transferor and the transferee, (ii) stating the name and mailing and
residence address of the transferee, and (iii) stating the desired
effective date of such change of ownership.  If the transferee fails to
execute a Debenture Agreement, the transferee's signature on the
instructions of transfer will be deemed to constitute the transferee's
assent to the terms of the Debenture and the Debenture Agreement.

     Section 10.03.  Registration of Transfer.  Transfer of the Debenture
shall be registered upon the Company's register of Debentures following the
Company's receipt of all documents necessary to effect transfer in
accordance with Section 10.02.  Such documents may be either personally
delivered by the transferor or transferee or mailed to the Company in
accordance with Section 15.01 hereof.

     Section 10.04.  Effective Date of Transfer.  The effective date of the
transfer recorded on the Company's register of Debentures shall be the date
requested in the instructions of transfer; the effective date shall not,
however, precede the date of the most recent payment date of interest with
respect to such Debenture.  In the event such date precedes the date of the
most recent payment of interest on the Debenture or if the desired date is
omitted from the instructions of transfer, the Company may in its
discretion honor the transfer, and, in such case, the effective date of
transfer shall be the first date at which the Company is in receipt of all
of the items required by Section 10.02 hereof.

     Section 10.05.  Transferee as Holder.  Upon completion of a transfer
in accordance with the provisions provided in this Article X, such
Transferee shall be considered the Holder as if the transferee had been the
original party to execute this Agreement.

     Section 10.06.  Issuance of New Certificates.  Upon a transfer in
accordance with this Article X, and upon delivery by the transferor of his,

                                                                      B-24

her, or its Debenture certificate representing the Debenture being
transferred, the Company shall cancel such Debenture certificate and shall
issue a new certificate in the transferee's name.  Such new certificate
shall be issued in accordance with Article II hereof, and its provisions
will be identical to those of the old Debenture certificate except as to
the Holder's name and the date of execution, which date on the new
certificate shall be the same as the effective transfer date in accordance
with Section 10.04 hereof.

     Section 10.07.  Legend on Debenture.  The Debenture shall bear the
following legend:

     "THIS Debenture HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
     1933, AS AMENDED (THE "ACT") OR THE SECURITIES LAWS OF ANY STATE,
     AND HAS BEEN ISSUED PURSUANT TO EXEMPTIONS FROM SUCH REGISTRATION
     AND QUALIFICATION REQUIREMENTS.  THIS Debenture MAY NOT BE SOLD,
     TRANSFERRED, OR ASSIGNED WITHOUT THE PERMISSION OF THE ISSUER AND
     UNLESS THIS Debenture SHALL HAVE BEEN DULY REGISTERED UNDER THE ACT
     AND REGISTERED OR QUALIFIED UNDER APPLICABLE STATE SECURITIES LAWS,
     OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER,
     REGISTRATION AND QUALIFICATION OF THE Debenture SHALL NOT BE
     REQUIRED.  THIS DEBENTURE IS SUBJECT TO AND ITS TRANSFER IS
     RESTRICTED BY THE TERMS AND PROVISIONS OF THAT CERTAIN DEBENTURE
     AGREEMENT, DATED ______________, EXECUTED BY AND BETWEEN THE
     COMPANY AND THE HOLDER OF THIS DEBENTURE, A COPY OF WHICH IS ON
     FILE IN THE OFFICES OF THE COMPANY."


                                 ARTICLE XI

                             REGISTRATION RIGHTS

     Section 11.01.  Registration on Request.  Upon the written request of
any holder or holders of at least 25% in the aggregate principal amount of
the Debentures and/or shares of Common Stock ("Shares") issued upon 
conversion of such Debentures, which request shall state the intended
method of disposition by such bolder or holders and shall request that the

                                                                      B-25

Company effect the registration of all or part of such Shares, or the
Shares issuable upon the conversion of such Debentures, or both, under the
Securities Act of 1933, as amended (the "Act"), the Company will promptly
give written notice of such requested registration to all holders of
outstanding Debentures and Shares, and thereupon will use its best efforts
to effect the registration under the Act of:

     (a)  the Shares which the Company has been so requested to register,
     for disposition in accordance with the intended method of disposition
     stated in such request, and

     (b)  all other outstanding Shares, or Shares issuable upon the
     conversion of Debentures, the holders of which shall have made written
     request (stating the intended method of disposition of such securities
     by such holders) to the Company for registration thereof within thirty
     (30) days after the receipt of such written notice from the Company,

all to the extent requisite to permit the disposition (in accordance with
the intended methods thereof as aforesaid) by the holders of the Shares so
registered and to maintain such registration in effect for a period of
twenty-four (24) months from the closing of the private placement under the
Private Placement Memorandum; provided, that the Company shall not be
required to register or use its best efforts to effect any registration of
Shares under the Act pursuant to this Section 11.01 more than once. 

     The Company shall have no obligation to register or use its best
efforts to effect any registration of Shares under the Act pursuant to this
Article XI which would be in conflict with the obligations of any holder or
holders of Debentures and/or Shares under any confidentiality agreement
between such holder or holders and the Company entered into in connection
with the offering of the Debentures to such holder or holders.

     Section 11.02.  Incidental Registration.  If the Company at any time
proposes to register any of its securities under the Act (otherwise than
pursuant to Section 11.01 and other than a registration on Form S-8, or the
form, if any, which supplants such Form), it will each such time give
written notice to all holders of outstanding Debentures and Shares of its

                                                                      B-26

intention to do so and, upon the written request of any such holder made
within thirty (30) days after the receipt of any such notice (which request
shall specify the Shares intended to be disposed of by such holder and
state the intended method of disposition thereof), the Company will use its
best efforts to cause all such outstanding Shares, or Shares issuable upon
the conversion of Debentures, the holders of which shall have so requested
the registration thereof, to be registered under the Act to the extent
requisite to permit the disposition (in accordance with the intended
methods thereof as aforesaid) of the Shares so registered; provided that,
if in the good faith judgment of the managing underwriter or underwriters
of a then proposed public offering of the Company's securities, such
registration of such Shares would materially and adversely affect such
public offering, then in such event the number of Shares and other
securities to be registered by the Company shall each be proportionally
reduced to such number as shall be acceptable to the managing underwriter.

     Section 11.03.  Registration Procedures.  If and whenever the Company
is required to use its best efforts to effect or cause the registration of
any Shares under the Act as provided in this Article XI, the Company will,
as expeditiously as possible:

     (a)  prepare and file with the Securities and Exchange Commission (the
     "Commission") a registration statement with respect to such Shares and
     use its best efforts to cause such registration statement to become
     effective;

     (b)  prepare and file with the Commission such amendments and
     supplements to such registration statement and the prospectus used in
     connection therewith as may be necessary to keep such registration
     statement effective for such period not exceeding twenty-four (24)
     months from the closing of the private placement under the Private
     Placement Memorandum as may be necessary to comply with the provisions
     of the Act with respect to the disposition of all Shares covered by
     such registration statement during such period in accordance with the
     intended methods of disposition by the seller or sellers thereof set
     forth in such registration statement;


                                                                      B-27

     (c)  furnish to each seller of such Shares such number of copies of
     such registration statement and of each such amendment and supplement
     thereto (in each case including all exhibits), such number of copies
     of the prospectus included in such registration statement (including
     each preliminary prospectus and, if any seller shall so request, a
     summary prospectus), in conformity with the requirements of the Act,
     and such other documents, as such seller may reasonably request in
     order to facilitate the disposition of the Shares owned by such
     seller;

     (d)  use its best efforts to register or qualify such Shares covered
     by such registration statement under such other securities or blue sky
     laws of such jurisdictions as each seller shall reasonably request,
     and do any and all other acts and things which may be reasonably
     necessary or advisable to enable such seller to consummate the
     disposition in such jurisdictions of the Shares owned by such seller;
     and

     (e)  notify each seller of any such Shares covered by such
     registration statement, at any time when a prospectus relating thereto
     is required to be delivered under the Act within the period mentioned
     in subdivision (b) of this Section 11.03, of the happening of any
     event as a result of which the prospectus included in such
     registration statement, as then in effect, includes an untrue
     statement of a material fact or omits to state any material fact
     required to be stated therein or necessary to make the statements
     therein not misleading in the light of the circumstances then
     existing, and at the request of any such seller prepare and furnish to
     such seller a reasonable number of copies of a supplement to or an
     amendment of such prospectus as may be necessary so that, as
     thereafter delivered to the purchasers of such Shares, such prospectus
     shall not include an untrue statement of a material fact or omit to
     state a material fact required to be stated therein or necessary to
     make the statements therein not misleading in the light of the
     circumstances then existing.

     Section 11.04.  Registration Expenses.  All expenses incident to the

                                                                      B-28

Company's performance of or compliance with this Article XI, including,
without limitation, all registration and filing fees, fees and expenses of
complying with securities or blue sky laws, printing expenses and fees and
disbursements of counsel for the Company and of independent pubic
accountants, but excluding underwriting commissions and discounts, shall be
borne by the Company.  

     Section 11.05.  Indemnification.  

     (a)  In the event of any registration of any Restricted Shares under
     the Act pursuant to this Article XI, the Company will, to the extent
     permitted by law, indemnify and hold harmless the seller of such
     Shares and each underwriter of such securities and each other person,
     if any, who controls such seller or underwriter within the meaning of
     the Act, against any losses, claims, damages, or liabilities, joint or
     several, to which such seller or underwriter or controlling person may
     become subject, under the Act or otherwise, insofar as such losses,
     claims, damages, or liabilities (or actions in respect thereof) arise
     out of or are based upon (i) any untrue statement or alleged untrue
     statement of any material fact contained, on the effective date
     thereof, in any registration statement under which such securities
     were registered under the Act, any preliminary prospectus or final
     prospectus contained therein, or any amendment or supplement thereto,
     or (ii) any omission or alleged omission to state therein a material
     fact required to be stated therein or necessary to make the statements
     therein not misleading; and the Company will reimburse such seller and
     each such underwriter and each such controlling person for any legal
     or any other expenses reasonably incurred by them in connection with
     investigating or defending any such loss, claim, damage, liability, or
     action, provided that the Company shall not be liable in any such case
     to the extent that any such loss, claim, damage, or liability arises
     out of or is based upon an untrue statement or alleged untrue
     statement or omission or alleged omission made in such registration
     statement, any such preliminary prospectus, final prospectus,
     amendment or supplement in reliance upon and in conformity with
     written information furnished to the Company through an instrument
     duly executed by such seller or underwriter specifically for use in

                                                                      B-29

     the preparation thereof.

     (b)  The Company may require, as a condition to including any Shares
     in any registration statement filed pursuant to Section 11.03, that
     the Company shall have received an undertaking satisfactory to it from
     the prospective seller of such Shares and from each underwriter of
     such  Shares, to indemnify and hold harmless (in the same manner and
     to the same extent as set forth in subdivision (a) of this Section
     11.03) the Company, each director of the Company, each officer of the
     Company who shall sign such registration statement and any person who
     controls the Company within the meaning of the Act, with respect to
     any statement or omission from such registration statement, any
     preliminary prospectus or final prospectus contained therein, or any
     amendment or supplement thereto, if such statement or omission was
     made in reliance upon and in conformity with written information
     furnished to the Company through an instrument duly executed by such
     seller or underwriter specifically for use in the preparation of such
     registration statement, preliminary prospectus, final prospectus,
     amendment, or supplement. 

     (c)  Promptly after receipt by an indemnified party of notice of the
     commencement of any action involving a claim referred to in the
     preceding subdivisions of this Section 11.05, such indemnified party
     will, if a claim in respect thereof is to be made against an
     indemnifying party, give written notice to the latter of the
     commencement of such action, provided that the failure of any
     indemnified party to give notice as provided therein shall not relieve
     the indemnifying party of its obligations under the preceding
     subdivisions of this Section 11.05.  In case any such action is
     brought against an indemnified party, the indemnifying party will be
     entitled to participate in and to assume the defense thereof, jointly
     with any other indemnifying party similarly notified to the extent
     that it may wish, with counsel reasonably satisfactory to such
     indemnified party, and after notice from the indemnifying party to
     such indemnified party of its election so to assume the defense
     thereof the indemnifying party will not be liable to such indemnified
     party for any legal or other expenses subsequently incurred by the

                                                                      B-30

     latter in connection with the defense thereof.  No indemnifying party,
     in the defense of any such claim or litigation, shall, except with the
     consent of each indemnified party, consent to entry of any judgment or
     enter into any settlement which does not include as an unconditional
     term thereof the giving by the claimant or plaintiff to such
     indemnified party of a release from all liability in respect to such
     claim or litigation.

     Section 12.01.  Continuation of Terms of Agreement.  Nothing contained
in this Agreement or in the accompanying Debenture shall prevent any
consolidation or merger of the Company with or into any other corporation
or association, or any conveyance of the business, assets, and properties
of the Company as a whole or substantially as a whole, to any other
corporation or other entity, provided that all terms and conditions of this
Agreement, including payment, to be observed and performed by the Company
shall be expressly assumed by the successor entity formed by or resulting
from any such merger or to which any such conveyance shall have been made.

     Section 12.02.  Rights of Successor.  If the Company or any successor
entity is consolidated or merged with or into, or shall make a conveyance
to, any other corporation or other entity, as permitted and upon the terms
provided in this Article XII, the entity formed by or resulting from such
consolidation or merger or to which such conveyance shall have been made
shall succeed to and be substituted for the Company, with the same force
and effect as if it had been named in, and had executed, this Agreement,

                                 AMENDMENTS

     Section 14.01.  Without Consent of Holder.  The Company may amend this
Agreement and the Debenture without the consent of the Holder:

          (a)  To cure any ambiguity, defect, or inconsistency;

                                                                      B-32

          (b)  To comply with any consolidation or merger of the Company
               with or into any other corporation, or to comply with any
               conveyance of the business, assets, and properties of the
               Company as a whole or substantially as a whole, to any other
               corporation or other entity, provided that the corporation
               complies with the terms of Article XII hereof; and

          (c)  To make any change that does not adversely affect the rights
               of the Holder.

     Section 14.02.  With Consent of Holder.  Subject to the terms of
Section 14.01, the Company may amend this Agreement or the Debentures with
respect to any matter with the written consent of the holders of at least
66 2/3 percent (66 2/3%) of the aggregate principal amount of the
outstanding Debentures.  However, without consent of each holder affected,
an amendment under this section may not:

          (a)  Reduce the rate of or change the time for payment of
               interest on any Debenture;

          (b)  Reduce the principal of or change the fixed maturity of any
               Debenture;

          (c)  Make any Debenture convertible into any securities other
               than as described in Section 8.01; or

          (d)  Make any change in this Section 14.02.

     Section 14.03.  Revocation and Effect of Consents.  Until an amendment
or waiver becomes effective, a consent to such amendment or waiver by a
holder of a Debenture is a continuing consent by such holder and every
subsequent holder of such Debenture, even if notation of the consent is not
made on any Debenture.  Any such holder or subsequent holder may, however,
revoke the consent as to his Debenture if the Company receives the notice
of revocation before the date the amendment or waiver becomes effective. 
An amendment or waiver becomes effective in accordance with its terms and
thereafter binds every holder of a Debenture.

                                                                      B-33

     Section 14.04.  Notation on or Exchange of Debentures.  The Company

certificates may issue new certificates that reflect the amendment or
waiver.
